5-Step Pre-Scan Checklist for OneDrive to OneDrive Migration

Shifting OneDrive from one Microsoft 365 tenant to another is an important task for companies with large-scale digital frameworks. A successful OneDrive tenant to tenant migration begins with a thorough pre-scan checklist that helps eliminate risk (zero risk assurance with CloudFuze), unearths hidden issues, and provides enterprise-ready readiness.

In this guide, we will walk you through a 5-step pre-scan checklist exclusively designed for Microsoft 365 tenant to tenant migrations, including OneDrive to OneDrive migration, which helps large businesses and IT leaders plan with accuracy and confidence.

Why Pre-Scan is Important in OneDrive for Business to OneDrive to Business Migration

Pre-scan is crucial in every Microsoft 365 tenant to tenant move, including OneDrive to OneDrive and SharePoint to SharePoint migration. It gives IT departments the scope to detect risks ahead of time, enhance migration planning, and ensure end user continuity.

A pre-scan:

1. Discovers incompatible file types, permission issues and corrupted links
2. Discovers content that will exceed Microsoft 365 storage limits
3. Discovers security and compliance concerns
4. Helps map users, groups and sharing permissions appropriately

Skipping this step results in failed transfers, lost data or cost delay, especially during departmental, geographic or regulated industry large-scale migrations.

5-Step Pre-Scan Checklist for OneDrive to OneDrive Migration

1. Inventory All OneDrive Users and Data Amounts

The first step of any successful OneDrive to OneDrive migration involves examining a complete list of OneDrive accounts and their respective data volumes. For large organizations, this proves to be helpful to:

1. Determine the total size including total number of OneDrive users and their data volume
2. Analyze approximate timeframe of the migration
3. Appropriately assign bandwidth requirement
4. Break users into priority, department, or region for staged migration

At CloudFuze, our Microsoft 365 tenant-to-tenant migration tool facilitates the entire process by providing precise user and data inventories. By removing massive manual labor and possible errors, IT staff are able to precisely and anticipatorily know what resources will be required for the migration and avoid surprises during implementation.

2. Evaluate File Types, Metadata and Sharing Permissions

All file types and metadata are not compatible or transferred completely in a OneDrive for business to OneDrive to business migration. Ignoring these aspects may cause file transfer failures, data context loss, or anticipated accessibility problems.

As a part of your pre-scan:

1. Make a note of unsupported file types like .tmp, .dll, .lnk, etc.
2. Identify external or anonymous share links which may compromise post-migration

With our Microsoft 365 tenant migration solution, we detect these factors in pre-scan enabling IT staff to reconfigure, tidy up, or alert users prior to migration.

Our OneDrive to OneDrive migration tool helps with 100% metadata preservation including version history and timestamps. Ready to test full metadata integrity in action? Start your no-risk pilot run with us and validate your migration strategy.

This forward-looking insight provides a smoother, more predictable process with reduced surprises and a helpdesk for tickets in the future.

3. Map User Accounts Between Source and Destination Tenants

Proper mapping of user accounts ensures access and collaboration consistency after migration. During the pre-scan:

1. Cross verify source and target usernames/email addresses
2. Mark duplicate or orphaned accounts

We make it easy with our Microsoft 365 to Microsoft 365 migration tool, which will automatically scan, map, and validate user accounts between tenants. For companies that want to have more control over the process, we also provide CSV-based user mapping, providing IT administrators complete freedom and flexibility to define account relationships.

Whether automated or manual, we guarantee your user mapping to be correct, so your users end up exactly where they are supposed to, with access they expect.

4. Permission and Sharing Conflicts

Permissions in one Microsoft 365 tenant do not necessarily translate neatly to another. Failing to account for this during migration can result in broken access, security holes, or compliance issues.

As part of your pre-scan, be sure to:

1. Detect custom or external sharing settings on files and folders
2. Inspect role-based access levels and permissions
3. Validate alignment with internal governance and external compliance policies

At CloudFuze, we assist enterprises in being able to detect and document these permissions and sharing settings ahead of time before the migration process even starts. This maintains governance, security, and user access in place throughout the migration process, particularly important for regulated industries.

By resolving these conflicts ahead of time, you eliminate risk and enable a smooth, secure transition for your users.

5. Consider Network Readiness and Throttling

Terabyte or petabyte-scale enterprise migrations of OneDrive content can put serious pressure on your network infrastructure. Proper planning can help prevent performance issues, user frustration, and delays in migration.

A pre-scan assists you to:

1. Estimate bandwidth requirements based on aggregate data volume and user spread
2. Detecting potential API throttling from SharePoint Online and Microsoft Graph

At CloudFuze, we offer sophisticated throttling control systems that eliminate these restrictions. Through active monitoring and regulation of data flow, our solution makes sure that your OneDrive tenant to tenant migration is uninterrupted, ensuring no disturbance to your users and business processes.

Step-by-Step Guide to Running a OneDrive to OneDrive Pre-Migration Scan in CloudFuze

Start by creating an account in the CloudFuze webapp.

1. Step 1: Go to Pre-Migration and then Run Pre-Migration. Choose the appropriate OneDrive source cloud (e.g., “mia” or “Erik e”) from the dropdown to begin scanning that environment.
   
2. Step 2: Verify user selections and review usage data (e.g., 10.55 GB used) before running the pre-migration scan.
   
3. Step 3: Now choose the metadata types like versions, embedded links, shared links, collaborators, and only root folders to include in the pre-scan. Then click on the “Run Pre-Migration” button.
   
4. Step 4: Review the Pre-Migration Workspaces page to check the scan status (e.g., “Inprogress”) and view metadata options (e.g., versions, embedded links) for each user’s OneDrive workspace. You can download the OneDrive to OneDrive migration report (in the CSV format).
