We are panning for upgrade from 7-mode Data Ontap 8.1.4P4 to 8.2.4P6. I have generated upgrade adviser and looks fine.
But my filers contain 32-bit aggregates. My query is, upgrade adviser did not suggested to upgrade aggr to 64-bit. Other than benifits with 64-bit aggr, Can I ignore upgrading 32-bit aggr.
If yes I can go ahead with Data Ontap upgrade as usual right.
if not, obviously I have to update 32-bit aggr.
Solved! SEE THE SOLUTION

The following TR has about the most in-depth discussion I've seen about 32/64-bit aggregates:
The bottom of page 8 has a "benefits of 64-bit" section and there's also good background information on requirements, procedures, etc.
Since 32-bit support doesn't drop off until 8.3 (which is a non-issue for 7mode) you're not "forced" to go to 64-bit. However, if you wanted to perform a copy-free transition of this system over to ONTAP9 or something else along those lines, you'd need to be 64-bit. That said, as JGPSHNTAP points out, 64-bit aggregates are really the way to go, especially if you're anywhere near the aggregate capacity on what you're running and might want to add new disk/etc (and might bump into the 16TB limit).
