Because volume SnapMirror works at the block level, the source and destination must both be FlexVol volumes
in the same aggregate type. The source and destination of a volume SnapMirror relationship must either both
be FlexVol volumes in 32-bit aggregates or both be FlexVol volumes in 64-bit aggregates. Therefore you
cannot create a volume SnapMirror relationship from a FlexVol volume in a 32-bit aggregate to a FlexVol
volume in a 64-bit aggregate or vice versa.
