Currently all of our filers are running ONTAP 7.3.x and we are looking at upgrading to 8.x and perhaps buying some disks/shelves that require 8.x. We would also like to convert to 64 bit aggrs to get beyond the 16T size limit.
Same here.
As I understand it, there is no way to upgrade an existing 32 bit aggr to 64 bit in place,
yet. (Talk to a technical sales rep).
you need to copy the data. Furthermore, you cannot volume snapmirror 32 bit to/from 64 bit.
Not strictly true. You cannot volume snapmirror from 32 bit to 64 bit. You can do a qtree snapmirror from a 32bit to a 64bit volume. In that respect, it's comparable to the migration from a tradvol to a flexvol, if you were around long enough to recall that.
I presume you can ndmpcopy 32 bit to/from 64 bit. How about "vol copy" ?
Dunno. I presume ndmpcopy and vol copy work from 32bit to 64bit, but I haven't tried.
Is anyone running 8.x and migrating from 32bit to 64bit aggrs? How are you doing it?
8.0 is useless for us at it is, since there's no easy way to upgrade the data in place, and running 8.0 on some platforms will just cause snapmirror incompatibilities. (We've actually downgraded some new hardware that was shipped with 8.0 to 7.3).
We will be waiting for the inplace conversion to be ready and tested before upgrading our servers.
