Hot Unplug Shelves but need to move disks first - HELP!

Hello,

I need to move all my SATA shelves from our 7 mode system to CDOT. However, we do not have enough swing kit to do both 7 mode controllers aggr's at once.

So, I want to migrate all data from 1 filer's aggr and then destroy that aggr, hot unplug the shelf and then rinse and repeat.

BUT, 

2 of the SATA shelves have 12 disks each assigned to each controller.

So,

Is there a way to move the disks between controllers \ aggr's.

e.g. remove disk 1 from node 1 aggr 1 then remove ownership and assign to node 2. Whilst simultaneously removing disk 1 from node 2 aggr 1

Is it the disk replace command? or is there an easier way?
