We are moving from vSphere 5.0 to vSphere 6.7 with vSAN.
we are running two different vCenters
what i would like to do is add our current Tegile SAN to our new vSphere 6.7
i would turn off the VM on our older vSphere 5.0 and remove it from vCenter. then on the new vCenter i would add it. then migrate it over to our vSAN.
i have heard that this is a problem because the data might get corrupted. because the old SAN would be on two different Data centers the LUN would be presented to both old and new ESXi Hosts.
they have said the only way to do this would be to turn off all of the vm's on the old lun, then unmap it to the old ESXi hosts. then map it to the NEW ESXi hosts.
