I have some 4.1 & some 5.0 hosts, all of which share a common iSCSI datastore. I'm trying to determine the best way to migrate live VMs from the 4.1 hosts to the 5.0 hosts. There doesn't appear to be any benefit of having the hosts in a cluster. I can't migrate both the host and datastore in one step without the VM being powered down. To move the VM live, I have to change the host from 4.1 to 5.0, then change the datastore from 4.1 local to iSCSI, then change the datastore to 5.0 local.
I know this isn't ideal but our iSCSI datastore is too slow to run production VMs. We're going to use it for this migration and subsequently for backups only.
What are my options for migrating live VMs from a 4.1 local datastore to a 5.0 local datastore?
thanks!
