AD errors in DC after a migration to Azure

I recently used Carbonite Migrate to migrate a couple of servers to Azure. One is fine, the other is my DC and I am getting errors in AD - cannot find domain, cannot load forest etc.

Errors from DCDiag - Advertising (error 1355). Netlogons (error 67), Replications (0x2105), NTDS (access denied), GPO errors because it cannot access a DC, my .local domain fails (error 1355)

Some are fine DNS,FrsEvent, DFSREvent, SysVolCheck, KccEvent, KnowsOfRoleHolders, MachineAccount, NCSecDesc, ObjectsReplicated, RidManager, VerifyReferences, ForestDNSZones, DomainDNSZones, Schema

I am looking for a way to recover this - I have a backup locally that would take a couple of days to upload after I prepare the vhd for upload to Azure and I am trying to avoid this

    It isn't recommended to backup / restore a domain controller when multiple are involved. Better option is to stand up new ones in the new space. Other than that I'd check that the ports are flowing between networks.
