Please point me to the link or document which explain step by step QSM procedure to migrate data between 32bit aggregate and 64bit aggregate for the volumes with snapshot.
I have volumes with snapshots with the default name(hourly./nightly./weekly.)
Thanks and Regards,

As far as I am concerned, nothing changed since you have posted a very similar question few months ago (http://communities.netapp.com/message/53569#53569), and the answer to it is still valid:
- either wait for ONTAP 8.1
- or do a tedious migration following KB article https://kb.netapp.com/support/index?page=content&id=1012182

I had gone through the KB article you gave and it was very helpful.
But I am confused about how to migrate default snapshots which got created with name hourly, nightly and weekly.
Can you please explain how to migrate default snapshots (snapshots with name hourly/nightly/weekly ) to the destination?

Correct me if I'm wrong, but I think it's possible (but not easy) to migrate the snapshots.
After you have initialized the snapmirror:
snapmirror update -s nightly.0 -c nightly.0 -S src:/vol/<srcvol>/<srcqtree> /vol/<dstvol>/<dstqtree>
snapmirror update -s nightly.1 -c nightly.1 -S src:/vol/<srcvol>/<srcqtree> /vol/<dstvol>/<dstqtree>
snapmirror update -s nightly.2 -c nightly.2 -S src:/vol/<srcvol>/<srcqtree> /vol/<dstvol>/<dstqtree>
snapmirror update -s nightly.3 -c nightly.3 -S src:/vol/<srcvol>/<srcqtree> /vol/<dstvol>/<dstqtree>
you have to do it for every snapshot!

If we try to update snapmirror with the automatically created snapshots (hourly/nightly/weekly) it gives following message:
snapmirror update -s weekly.0 -c weekly.0 -S /vol/<src_vol>/<src_qtree> -w /vol/<dstvol>/<dstqtree>
Cannot transfer a snapshot with a name in the format of
an automatically created snapshot: weekly.0.
Select a different snapshot, or rename the snapshot you have chosen.
snapmirror update [-k <n>][-s <src_snap>] [-c <dst_snap>][-S [<srcfiler>:]<srcpath>][-w] [<dstfiler>:]<dstpath>
in which <srcpath> and <dstpath> are
<volname> or </vol/volname/qtreename>
- forces snapmirror update of snapmirror destination
That’s why i posted this on community to find out ways to migrate automatically created snapshots.
I can see the option to rename the snapshot and migrate it. But it will manual task to remove the snapshots after they expires.
