Moving disks to another controller (head)

Hi Toasters,

I need to physically move some disks/aggregates to another controller. Do you see anything wrong with this procedure?

1) upgrade DOT to the same version on both heads (7.3.3)

2) shut down and power off both heads

3) physically move the disk shelves

4) boot the destination head in maintenance mode and use "disk assign" to take ownership of the moved disks

5) boot the destination head normally

6) aggr online the foreign aggregates

I am concerned about step 4 above. Will it work or do I need to boot the source filer in maintenance mode and change the disk ownership to the destination head before moving the disks?

In step 5 some of the foreign aggregates will have names that conflict with native aggregates. I presume that when ONTAP boots it will automatically rename the foreign aggrs as necessary. Or must I rename them on the source filer beforehand?

I know that some of you do this routinely, so I appreciate any words of advice.
