Migrating Repository LUN from RAID group to storage pool

Hi

we need to Migrating Repository LUN from RAID group to storage pool LUN (VNX5600). I am thinking about the following steps

Create a New Lun on storage pool

Migrate repository LUN

Delete the previous LUN

Create a New LUN with same ID as the orignal Reposirory LUN

Migrate the Lun again.

Recovery point will be powered off during this activty

will this be ok or wrong or am i missing anything

thanks
