This should answer all your questions.

So in short to answer your question, I have got some points listed below from the above link.
You cannot move the following types of volumes:
1. A volume from a 32-bit aggregate to a 64-bit aggregate, or from a 64-bit aggregate to a 32-bit aggregate
2. The source volume should not be exported to NFS or CIFS clients when the volume move operation is in progress.
Note: There is a small window of time when you can export the source volume over NFS or CIFS before the volume move enters the cutover phase. However, if you do so, the cutover phase might not be successfully completed. If the cutover phase is not completed, there is no disruption to SCSI clients because the volume move rolls back to continue with the data copy phase.
