BitTitan MigrationWiz is the most widely used third-party migration platform for Microsoft 365 tenant-to-tenant moves. For enterprises merging after acquisition, divesting business units, or consolidating regional tenants, it automates the transfer of mailboxes, OneDrive files, SharePoint sites, and Teams data with zero infrastructure and zero user downtime.
What Is BitTitan MigrationWiz?
BitTitan MigrationWiz is a 100% cloud-based SaaS migration platform designed to automate data transfers between email systems, collaboration platforms, and cloud storage services. Unlike traditional migration tools that require on-premises servers, VPNs, or complex infrastructure, MigrationWiz operates entirely through a web-based console — you create a project, configure endpoints, and start migrating data within minutes.
For Microsoft 365 tenant-to-tenant migrations, BitTitan is particularly valuable because Microsoft provides no native tool for moving data between two Microsoft 365 tenants. While you can use PowerShell scripts for basic mailbox migration, anything involving OneDrive, SharePoint, Teams, or complex permission mapping requires a third-party platform — and BitTitan is the market leader in this space.
100% Cloud-Based
No servers, no VPNs, no infrastructure. Log in through your browser and start migrating immediately.
Parallel Processing
Migrates multiple mailboxes and workloads simultaneously, scaling from 1 user to thousands.
Zero Downtime
Users continue working normally. Data copies in the background with delta sync until final cutover.
What Data Does BitTitan MigrationWiz Transfer?
The specific data BitTitan can migrate depends on the license type you purchase. Not all licenses cover all workloads — understanding the difference is critical when scoping a tenant-to-tenant project.
Exchange Online
Inbox, custom folders, email messages, contacts, calendars, tasks, notes, mailbox rules, out-of-office settings, delegate permissions
OneDrive for Business
All personal files, folder structures, sharing permissions, version history (configurable), file metadata, sync settings
SharePoint Online
Team sites, communication sites, document libraries, lists, page content, site permissions, content types, metadata
Microsoft Teams
Teams & channels, channel files & documents, channel tabs, team memberships, chat history (TMB license), meeting recordings
PST Archives
Import PST files directly into Exchange Online mailboxes, maintaining folder structure and item metadata
Attachments & Large Items
All email attachments regardless of size, with special handling for very large files through chunked transfer
S/MIME encrypted messages are migrated as-is — they remain encrypted at the destination and can be decrypted with the same certificates. BitTitan does not decrypt or inspect message contents during transfer.

When Do Enterprises Need BitTitan for Tenant-to-Tenant Migration?
Not every Microsoft 365 tenant move requires BitTitan. For simple mailbox-only migrations with under 50 users, native Microsoft tools or IMAP-based approaches may be sufficient and more cost-effective. But as soon as your project involves multiple workloads, complex permissions, or tight timelines, BitTitan becomes the smart choice.
Mergers & Acquisitions
When two companies merge, they each bring their own Microsoft 365 tenant. BitTitan consolidates Exchange mailboxes, OneDrive files, SharePoint sites, and Teams channels into a single unified tenant — while maintaining coexistence throughout the transition period.
Divestitures & Spin-offs
A parent company spinning off a subsidiary needs to split one tenant into two. BitTitan migrates selected users and their data to the new independent tenant, preserving folder structures, permissions, and collaboration settings.
Tenant Consolidation
Large organizations often end up with multiple tenants from acquisitions or regional setups. BitTitan merges these into one global tenant, centralizing IT management and reducing licensing overhead.
Domain Rebranding
Companies undergoing rebranding may want a clean tenant with updated naming conventions. BitTitan facilitates a full data migration to a new tenant while the old one remains operational during the transition.
How BitTitan MigrationWiz Works: Technical Overview
Understanding the underlying mechanics helps IT teams plan migrations effectively and set realistic expectations for stakeholders.
Endpoint Configuration
15 minutesConnect MigrationWiz to your source and target Microsoft 365 tenants.
- Provide global admin credentials for both source and target tenants
- Grant OAuth consent for MigrationWiz to access Exchange, OneDrive, SharePoint, and Teams APIs
- Enable modern authentication and MFA exemptions for the migration service account
User & Project Setup
30-60 minutesCreate migration batches and map source users to target users.
- Upload CSV file with source email, target email, and license type for each user
- Organize users into logical batches (by department, geography, or priority)
- Configure migration settings: date filters, folder exclusions, large item handling
Pre-Stage Migration
Hours to daysMigrate the bulk of historical data before the cutover date.
- MigrationWiz copies all emails, files, and data from source to target in the background
- Users experience zero disruption — source tenant remains fully operational
- Real-time dashboard shows progress per user, data volume, and any errors
Delta Sync & Cutover
1-2 hoursCapture changes since pre-stage, then switch users to the target tenant.
- Run delta sync to migrate new emails and files created since the pre-stage
- Update MX records and DNS to point to the target tenant
- Users reconfigure Outlook and mobile devices to connect to the new tenant
BitTitan vs AvePoint vs Quest: Migration Tool Comparison

How Workspace Migration Uses BitTitan — And Goes Beyond It
BitTitan MigrationWiz is a powerful tool, but it is just that — a tool. The difference between a failed migration and a seamless transition is not the software; it is the expertise, planning, and support wrapped around it. Here is how we add value on top of BitTitan's automation.
Pre-Migration Discovery & Risk Assessment
Before touching BitTitan, we run a comprehensive tenant inventory: mailbox sizes, OneDrive usage, SharePoint site complexity, Teams channel count, third-party app dependencies, and compliance requirements. This produces a migration scope document that prevents surprises mid-project.
Strategic Batch Planning
BitTitan lets you create batches, but deciding which users go in which batch — and in what order — requires understanding business priorities, interdependencies, and communication workflows. We design migration waves that minimize disruption to critical teams.
Real-Time Error Resolution
When BitTitan flags an error (throttling, permission denied, oversized item), our engineers diagnose and resolve it immediately — not in tomorrow's standup. We monitor every batch in real-time and intervene before small issues become project blockers.
User Mapping & Permission Preservation
BitTitan migrates the data; we ensure the data is usable. SharePoint permissions, calendar delegates, shared mailbox access, and Teams memberships all require careful user identity mapping between source and target tenants. We build and validate these mappings so nothing breaks.
30-Day Post-Migration Support
After cutover, users inevitably encounter issues: missing calendar entries, broken sharing links, confused Outlook profiles. Our 30-day support period includes a dedicated engineer who knows your project — not a generic helpdesk queue.
Flexible Licensing Strategy
We do not force BitTitan on every project. For simple mailbox-only migrations, we use native Microsoft tools and pass the savings to you. For full-suite tenant moves, we procure the right BitTitan license tier (Mailbox, UMB, or TMB) so you never overpay.
BitTitan MigrationWiz Licensing Explained
BitTitan licenses are valid for 12 months from purchase and are consumed per user at the time of first use. Choosing the wrong license tier is a common and expensive mistake. Here is exactly what each tier covers.
- Exchange Online mailbox (up to 50GB)
- Inbox, folders, contacts, calendar
- Tasks, notes, rules, signatures
- Does NOT include OneDrive or SharePoint
- Does NOT include Teams
- Everything in Mailbox Migration
- OneDrive for Business files
- Personal SharePoint sites
- Unlimited data volume per user
- Does NOT include Teams channels
- Everything in User Migration Bundle
- Microsoft Teams channels & files
- Teams chat history migration
- Up to 100GB Teams/SharePoint data
- Full collaboration suite coverage
BitTitan licenses are consumed upon first use and cannot be reused for the same user in a different project. If you purchase a UMB license for a user and later realize you need TMB for Teams coverage, you must purchase a new TMB license for that user. We help you choose the right tier upfront to avoid double-purchasing.
Step-by-Step: Setting Up a BitTitan Tenant Migration Project
This is the practical setup guide IT teams need to configure their first MigrationWiz tenant-to-tenant project correctly.
Create the MigrationWiz Account
Sign up at migrationwiz.com with a work email. Purchase the correct license volume (Mailbox, UMB, or TMB) based on your scoping. Add the source Microsoft 365 tenant as an endpoint using global admin credentials with modern authentication.
Add the Target Tenant Endpoint
Add the destination Microsoft 365 tenant as a second endpoint. Ensure the target tenant has sufficient licenses for all migrating users. Verify domain ownership in the target admin center before proceeding.
Create a Migration Project
Select the project type: Mailbox, Document, Archive, or Team. For tenant-to-tenant moves, you typically need separate projects for Mailboxes, OneDrive, SharePoint, and Teams — or use the TMB bundle project if available.
Upload the User CSV
Prepare a CSV with columns: SourceEmail, TargetEmail, TargetEmailAddress (for UPN changes), and any custom fields. Upload to MigrationWiz. Review the user mapping preview to catch typos or mismatched domains.
Configure Advanced Options
Set date range filters (e.g., only migrate emails from the last 2 years). Configure folder exclusions if needed. Enable item-level error reporting. Set throttling behavior to respect Microsoft API limits.
Run Verify Credentials
Before starting migration, run the credential verification test for a subset of users. This catches authentication issues, MFA conflicts, or insufficient permissions before you waste license consumption.
Start Pre-Stage Migration
Launch the pre-stage migration for all users. Monitor the dashboard for errors, throttling events, and completion percentages. Address errors in real-time. This phase typically runs for hours to days depending on data volume.
Run Delta Sync & Cutover
Schedule the final delta sync for off-hours. Once complete, update MX records to point to the target tenant. Instruct users to reconfigure Outlook and mobile devices. Use DeploymentPro (included with UMB/TMB) for automated Outlook profile updates.
Common BitTitan Migration Issues & Troubleshooting
Throttling Errors (HTTP 429)
Symptom: Microsoft throttles API requests when too many are sent in rapid succession.
Resolution: Reduce migration concurrency in BitTitan settings. Increase wait time between API calls. Schedule migration during off-peak hours (nights/weekends).
Authentication Failures
Symptom: Global admin credentials fail or MFA blocks the MigrationWiz service account.
Resolution: Create a dedicated migration service account with MFA disabled. Ensure the account has global admin rights in both source and target tenants. Verify OAuth consent is granted.
Oversized Items
Symptom: Individual emails or files exceed the maximum transferable size.
Resolution: Configure large item handling in advanced options. For emails over 150MB, consider splitting attachments or using archive export. For SharePoint files over 15GB, use SharePoint native migration tool as supplement.
Permission Mapping Errors
Symptom: Shared folders or SharePoint permissions do not correctly map to target users.
Resolution: Review the user mapping CSV for typos or mismatched UPNs. Ensure all target users are fully provisioned with licenses before migration starts. Manually re-apply complex permission sets post-migration if needed.
Slow Migration Speed
Symptom: Migration is progressing slower than expected, extending the project timeline.
Resolution: Check Microsoft tenant throttling status in the BitTitan dashboard. Increase parallel migration threads if throttling is not active. Split large mailboxes into smaller batches. Verify network bandwidth is not a bottleneck.

Frequently Asked Questions
BitTitan MigrationWiz is a 100% cloud-based SaaS migration platform used to transfer email, documents, and collaboration data between cloud platforms. It is most commonly used for Microsoft 365 tenant-to-tenant migrations, Google Workspace to Microsoft 365 moves, and on-premises Exchange to cloud migrations.
Yes, BitTitan MigrationWiz can migrate Teams channels, files, tabs, and chat history through its Teams migration capabilities (included in the Tenant Migration Bundle). However, Teams chat history migration requires the Tenant Migration Bundle license and careful planning around conversation threading and channel membership.
BitTitan licenses are typically valid for 12 months from purchase and consumed upon use. Mailbox Migration licenses start around $11.99 per user (up to 50GB). The User Migration Bundle (UMB) runs roughly $15 per user and includes email, documents, and personal archives. The Tenant Migration Bundle (TMB) costs approximately $54-55 per user and covers mailboxes, OneDrive, and up to 100GB of Teams/SharePoint data.
No. BitTitan MigrationWiz is entirely cloud-based. There is no on-premises infrastructure to install, no servers to configure, and no VPN requirements. You simply log into the web console, create your migration project, and start moving data.
Migration speed depends on data volume, number of users, and source/destination throttling. A small business (under 50 users) typically completes in 1-3 days. Mid-market companies (50-500 users) take 1-2 weeks. Enterprise deployments (500+ users) may run 2-4 weeks. BitTitan runs continuously in the background with zero user downtime.
Yes. For straightforward mailbox-only migrations, we can use native Microsoft tools, PowerShell scripts, or IMAP-based approaches. However, if you need to migrate OneDrive, SharePoint, Teams channels, or complex permission structures, a third-party tool like BitTitan significantly reduces risk and manual effort. We assess each project and recommend the most cost-effective approach.
BitTitan provides detailed error reporting for every migrated item. Failed items are flagged with specific error codes, allowing targeted re-migration of only the affected data. We monitor migrations in real-time, address errors immediately, and run verification checks before final cutover to ensure 100% data integrity.
BitTitan preserves Exchange folder permissions, calendar delegate access, and OneDrive/SharePoint sharing links during migration. SharePoint site permissions require careful user mapping between source and target tenants to ensure the correct users receive access in the new environment.
