I got situation where I have old unmaintained (no maintenance license) VMWare enviroment running vcenter and esx servers in version 3.5. SAN is mixed iSCSI/NFS from two IBM N3300. All of this is going to be removed from use. Then I got new shiny vCenter 5.1 enviroment (new licenses), SAN is iSCSI from EMC VNXe.
I was just wondering if I could actually mount the old N3300 on new vcenter, start VM's and storage vmotion them away? But how VMWare reacts if storage is mounted on two different clusters? I probably should remove storage from old vcenter before mounting it to new one?
