Re: Migrating from 5.0 to 5.5

The VMs are indeed stored within the LUNs.  So as a basic list of tasks, would I:

1. Shutdown all the VM's, and put the hosts into maintenance mode?
2. Remove/unregister all the VMs that are on the old 5.0 environment?
3. Unmount the LUNs on the old 5.0 environment?
4. Mount the LUNs on the new 5.5 environment?
5. Register the VMs within the 5.5 environment?
6. Startup the VMs, and upgrade VMware tools?

Does this sound like a good basic task list?  I can obviously sort out the technical aspects myself, but I just need someone to verify that this is a sound process to follow.
