Just to add a few points
I haven't seen it documented in many places but in order to go from pre 8.2.1 to 8.3 if you have 32 bit aggregates then you need to do a stepwise upgrade, upgrade from pre-8.2.1 to 8.2.1, convert all the aggregates to 64 bit and then upgrade to 8.3 as 32 bit aggrs are not supported in 8.3.
If you mirror from a 32bit aggregate to a 64 bit aggregate the 32 bit aggregate is downgraded to a 32 bit aggregate while the snapmirror is active. On breaking the snapmirror the 32bit destination aggregate is converted back to 64bit. (YOu can see this in the messages log)
We have done a number of 32-64 bit upgrades on 7-mode but did have one instance where during the upgrade of one of the volumes in the agggregate to 64 bit it became inconsistent and we had to mirror the volume back from another site to recover the data.
