I'm actually in the middle of a similar migration between storage providers.
We're moving from Equalogic to Compellent so I can't speak to the specifics of
the EMC unit but in general the process consists of:
Add storage specific tools for new storage
(this won't apply in your case since you're going to a VM
presented volume)
Add the new volume
Clone the data
Take the old volume offline (disk management)
Disconnect the volume via the iSCSI interface
Swap the drive letter on the new volume
Process any storage specific needs to prevent further access / delete
the volume/LUN from storage
Uninstall the old storage specific tools from the server
I've done about a dozen over the last few weeks, and actually considered
whether we should stay with iSCSI connected or VM presented. The process is
essentially the same with the exception of the first item as noted above. We
decided to stay iSCSI because of advantages with our backup software, but
otherwise VM presented is less management.

Subject: [NTSysADM] Potentially silly question: Detatching iSCSI drive in
server 2012R2
All,
I've got a file server that has one of its drives presented to the OS over
iSCSI (it lives on a VNXe 3100, which we are about to
decommission) using the EMC Powerpath software.
I'm robocopying the contents over the a new drive that's presented as a VMDK
(on a different SAN - we're decommissioning the VNXe) and will be switching
drive letters so that the new volume drive drive letter (and therefore the
shares) of the old volume.
I'm thinking that during a maintenance period I can just kill the old drive,
uninstall the EMC software and be done with it, probably with a reboot after
the deinstallation of the EMC software and the switch of the drive letters.
Has anyone done something similar with detaching an iSCSI volume lately, and
can share the experience?
Kurt
