Error Message: The amount of licenses required does not match the last assessment result. Please restart the migration.
Cause: The amount of required collaboration licenses is calculated during a Teams assessment. If the amount of required licenses increase by more than 5 after the assessment but before migration completes, the migration will fail with the error "The amount of licenses required does not match the last assessment result. Please restart the migration."
Resolution: Re-run the assessment and find out how many more licenses are required, purchase that amount of licenses, then re-submit the migration.
Note: Conversation histories are not watermarked. If a migration fails, previously migrated conversation histories will need to be removed before restarting the migration to prevent duplicate conversation histories in the destination.
