Compression is a good use case for an in-place upgrade without adding disks.
It doesn't work with 32bit aggregates.

Thanks for the reply. Does anyone know if NetApp plans to change the process anytime in the future? An "aggr modify 64bit-upgrade" would be really nice :-)
What exactly does a 64 bit aggr buy you if it also fits in a 32 bits aggr (as it obviously currently does)? (Besides wasting more space for metadata).
I think the whole point of 64 bit aggrs is to be able to be able to expand beyond 16T/aggr. If your current aggr is smaller than that... what's the benefit of going to 64 bit?
I've starting playing around with the 8.1 RC1 release. I want to upgrade some aggregates from 32 bit to 64 bit. From what I can tell, the only way to do this is to add additional disks to an existing aggregate. Is that correct?
I've got one filer with limited disks and don't want to add 1 additional disk to a raid group. I don't want to do all the associated reallocates to smooth out the data allocation.
