Cutover migration errors on mailboxes -> processor unhealty

Question

Hi,

I'm trying a cutover migration batch from Exchange 2010 to Office 365. I keep getting the error message below on certain mailboxes:

"Error: ProvisioningFailedException: Resource ‎'Processor‎' is unhealthy and shouldn‎'t be accessed."

I know for sure that my on-premise exchange server is healthy. CPU is not above 30%

What can I do about this error?

Hi vschelle85,

Based on my experience, the issue could be caused by many factors. Could you try the following things to see if there is any improvement?

1.  Delete the batch, and recreate a new batch to run cutover migration.
2.  Please make sure you install the latest update, and restart the server.

If the issue persists, please view the details in the right part of the migration batch page, and select one of the impacted user mailboxes. Then you can use Exchange Online PowerShell to run the following cmdlet.

Get-MigrationUserStatistics -Identity *** Email address is removed for privacy *** -IncludeReport | FL

Get-MigrationStatistics | fl

Get-MigrationBatch -Identity "the batch name"

I have sent a private message to you to request them.
