Issue/Introduction
Provide steps to remediate the issue and allow for successful vCenter vMotion's when using the VCGA
Symptoms: When attempting to migrate from the Cloud vCenter to the OnPrem vCenter(s) using the VCGA. The action is failing with the error, "The object 'vim.ResourcePool:resgroup-#' has already been deleted or has not been completely created" when attempting to vMotion using both "Cross vCenter vMotion" and "Change Compute and Storage." If able to get past the incompatibility error, the error "The vMotion failed because the destination host did not receive data from the source host on the vMotion network. Please check your vMotion network setting and physical network configuration and ensure they are correct" may be encountered even when all of the vMotion requirements are met.
Cause
This is caused by VMs referencing opaque networks within the Cloud vCenter.
Confirm if we are getting the incompatibility error through the VCGA for both a Cross vCenter vMotion and when selecting the Change Compute and Storage option
Confirm if we are getting the same error when attempting both a Cold and Hot vMotion
Confirm if we are getting the same incompatibility error when doing a Cross vCenter vMotion directly from the Cloud vCenter UI
Confirm if there are any opaque networks leftover from the NVDS to CVDS conversion (this can be seen from the vCenter Networking tab - a network is considered Opaque if is can be seen outside of the vmc-hostswitch group)
Steps to remove opaque networks:
Click on the opaque networks from within the vCenter Networking tab
Go to the "VM" tab for the opaque network
Confirm if there are any VMs or Templates showing for the network
If there are VMs showing under the network, consolidate any snapshots on the VM and confirm if the VM is showing up on the networking anymore
If there are templates showing up, convert the template to a VM and then back to a template
Once steps 4 and 5 have been completed for all VMs and Templates, the network should be removed and should only be seen under the vmc-hostswitch group
