In the process of moving from an old vCenter to a new vCenter (same storage) you might need consider some things
- What do you want to do and when?
- Commit snapshots? (consolidate disks)
- Remove floppys?
- Remove from old vCenter
- Add to new vCenter
- Add hardware?
- Add hotplug cpu/mem?
- Snapshot before upgrade virtual hardware?
- Hardware upgrade?
- New network name?
- Upgrade vmware tools (reboot?) ?
Scripts to help with this, both on the way down and up so it will be made exactly the same every time and dont do anything else than what is set out to do. Im not used to powershell so bare with me.
What if we have vm appliances with very old hardware versions? should those get upgraded directly or does it need more digging to see if its supported? In this version its not yet considered and if we have a CSV file with alot of vm’s we can migrate/move all these vms at once but in doing so you have little control over whats happening in your vCenter environment, letting this beast loose on 100+ vms might be bad for you hart.
