DONT use LUN migration on LUNs that are used for NAS file systems – especially when source and target have a different storage profile (would be in in different system pools)  I would suggest to use Replicator instead
Is it possible to perform a lun migration of a celerra lun using Unisphere tools to perform the migration? for example, clariion lun 50 which maps to nas disk d8, can I perform the operation to right-click / migrate lun 50 to a same size lun of the same disk type? Ie: lun migrate lun 50 which is Raid5 to a new lun configured as raid6, same size?  I'm not sure if I should ask this question in the Navisphere/Unisphere forum or in the Celerra forum.  thanks.
