Migration Failing

[MigrationGhost]

Migrating VMs from old 6.7 cluster to new 8.0 cluster and I have a few VMs that fail with error "invalid configurations on device 15"

See attached. 6TB VMs in size.

Have a look at this KB. https://kb.vmware.com/s/article/2051236

The article relates to 5.1 but the workaround may resolve your issue.

The suggestion is to remove the virtual network adapter before migrating, then re-adding it at the other end. It will involve downtime, but it might fix your issue.

Did you get any error/warning during migration wizard?

I've had similar issue in the past and rather than removing and adding the NIC I just changed the network associated with the card and then flipped it back and all was OK for me.
