Cisco UCS B-Series, vSphere 6.5, FAS2650 with iSCSI SAN boot.  Utilizing ESX storage vMotion for migration of virtual machines to new Datastores on new FAS2750 easy enough.  Considering using SnapMirror to migrate and cutover the iSCSI SAN boot LUNS to the new FAS2750.  Can anyone share procedure, experiences, tips on accomplishing this task. I have a general idea but would like to avoid pitfalls if possible.

 

Thank You!

Hey Don, it would go something like this:

Evac guests and shut down the host.
cut the volume over via snapmirror.   (leave old one in place as a failback).

Map the lun to a the host's  igroup. 
Change the boot targets in the UCS profile. 
Boot the host / verify. 

Remove the old boot lun.
