I have purchased a new server to host both my RDP servers that are running on a less than adaqute host and would like to move them to this new server/host. I am running ESXi 6.0 and have these servers registered on vSphere. The server(s) are using local storage but the new server is using SSD's vs 10k hard drives. Also, the new server has 10gb NIC's instead of 1gb NIC's so this should improve speed as well.
My question is can I move these two VM's from one host to another both at the same time or do I need to migrate one at a time. Also, on the current server I have two iSCSI connections to this host however I do not use storage on either of the NAS devices so do I need to disconnect the iSCSI connections before migration? If so how do I do this? I have looked on the net and found how to create the iSCSI connections but not how to remove them.
Also, is there way to backup the complete configuration of the host or will snapshots be enough if the migration goes bad and I need to revert back to the original server and configuration.
