Mailbox migration failing

Mailbox Migration failing with below error, we are migrating between 2 trusted domain using Exchange native migration.

We created this migration job 3 days ago but one of our engineer deleted it before we could Complete the migration, the job had synced succesfully.

So I recreated the Migration Job and everytime it fails with the below error, I have tried targeting a different database on the Target but same issue.

I have also confirmed the source and target Archive GUID's are the same as many web articles suggest this is the issue.

"The move request for user 'USER NAME' is invalid: Target archive database for the move doesn't match. Active Directory value: '(null)'. Move request value: 'DB01'.. --> The move request for user 'User Name' is invalid: Target archive database for the move doesn't match. Active Directory value: '(null)'. Move request value: 'DB01'.

Normally during a cross forest migration a disabled user account is created in the target domain. Try deleting that account if it was created and start again as new move.
Do you have an archive mailbox present for users in exchange. If you are doing a cross forest migration not hybrid way, then

Run PrepareMoveRequest script first and then ADMT and the move the mailboxes using below command:

New-MoveRequest -Identity "Distinguished name of User in Target Forest" -RemoteLegacy -TargetDatabase "E2K10 Mailbox Database Name" -RemoteGlobalCatalog "FQDN of Source DC" -RemoteCredential $Remote -TargetDeliveryDomain "Target domain name"
