Error: CrossTenantMigrationWithoutLicensePermanentException

Question

Hi there.

I'm proceeding with cross-tenant mailbox migration and after performing all prerequisites on source and target Tenants (Endpoint, Relationship, creation of Mail Users and assigning the ExchangeGuid & LegacyExchangeDN)

And by starting a migration batch I got the following error:

Status  Data migrated: 0 B (0 bytes)  Migration rate:  Error: CrossTenantMigrationWithoutLicensePermanentException: No license was found for the source recipient, 'user1@oldtenant.com', or the target recipient, 'user1@newtenant.com'. A Cross-tenant User Data Migration license is required to move a mailbox between tenants.  
Data consistency score: Perfect

Then I waited for couple of hours and started the Migration Batch again it seemed to be going good, but after one hour get the same error again.

The source (Mailbox) and target (Mailuser) accounts do have "Exchange Online (Plan 1)" license.

Is there any other thing to do to proceed with this migration?

Hi @Ahmed Nagy,

For cross-tenant migration, you may need to also assign Cross Tenant User Data Migration license.

I have same issue and when contacted , MS support redirected us to Godaddy. Where Godaddy already completed steps required but error remains same. Stuck!

Can anyone from MS let us know how to purchase that add-on if it exists ? I can't find it anywhere in Office 365 Billing>Purchase services>Details>Add-on.
