vCenter vMotion failing

vCenter failing during vMotion with an ‘Invalid configuration for device ’25’. I can vMotion VM’s between hosts without issue. I have not found any useful KB articles on the above error message. I can only vMotion both the CPU and storage.
I’ve double and triple-checked the vMotion settings. The environment is as follows.

ESXi 6.7
vSphere 6 Essentials Plus (CPUs) capacity 6 with the usage of 4.
vCenter Server 6 Essentials 1 instance

  1. If you can do a shared nothing vSphere vMotion (simultaneous host and storage migration) but can’t do a regular vMotion I would be checking that both hosts can see the same storage that the VM is currently associated with. Check ISO images / RDMs too.
