I'm working on a migration project and we have one final cluster to migrate. This cluster uses ACI in combination with the Cisco AVS. The AVS is not supported on ESXi 6.7 so I need to come up with a migration plan. But that is easier said than done... My suggested plan is to create a new VMM domain in ACI and point that to the new vCenter Server. This will create a DVS in the new vCenter Server. The next step would be to evacuate a host, disconnect it from the old vCenter Server and connect it to the new vCenter Server. The final step would be a cross vCenter vMotion from the old vCenter to the new vCenter. I could use the Cross vCenter Workload Migration Utility | VMware Flings but for this to work both vCenters must be in Linked Mode. Is it possible to configure this even after both vCenter Servers already have been installed?
The old vCenter is a Windows 6.0 U3i with an external PSC. The new vCenter is a VCSA 6.7 U3c with embedded PSC.
Any idea's how to do this migration?
