VCF 4.5.1 on VxRail 7.0.451 - BringUp Failure - Migrate VMs to Management port group - MigrateVmsToDifferentPortGroup

Dear Community,

I tried to setup a VCF 4.x in our LAB and then to upgrade to VCF 5.x for self training.

The VxRail self is already setup correctly and healthy. I deployed the Cloud Builder Appliance and filled out the Excel Sheet.

The Validation was fine and I started the Deployment Process.

Unfortunately I have always a bring up Failure at step "Migrate VMs to Management port group" ...

I already completly setup a VxRail again and tried it again. But I landed in the same Error.

The VCF Bringup LOG File show the following:
