It’s right there in 8.1 release notes:
Starting with Data ONTAP 8.1, you can replicate volumes by using SnapMirror between 32-bit and 64-bit volumes. For both synchronous and asynchronous volume replication, the SnapMirror source and destination volumes can be either 32-bit or 64-bit.

Andrey, George - thanks for the feedback
Anyone have a list of the test points? This one disables model checks -
testpoint -m Dfmutil -n disable-model-checks -e 1 -r 1 –q
Is there one for ontap version checks? Again - I am in pure test mode and have heard many conflicting stories - just want to see what's possible - we certainly were made to hold out for 8.1 for datamotion support for our upgrade plans.
Andrey - can you elaborate on your 8.1 statement ? Cite any TR's ?
thanks

On the other hand, Sync Snapmirror and regular Async Snapmirror are block based and do require that source and destination be the same type (either 32-bit or 64-bit).
It's no more so for 8.1 which OP has.
