Can a snapshot be restored from 4.1 to 4.2

Question:  Can a snapshot be restored from 4.1 to 4.2?

Answer:  NO!

Action Taken:  Ran a test on test system, and found the following
errors when trying to install a 4.1 snapshot on a 4.2 system.

Verifying Cluster Events on Individual Nodes

clsnapshot: Verification determined 11 error(s) occurred.  Please
correct any errors and retry.

It turns out that the changes were not made at all to the other
system.

It would appear from my test that you CANNOT apply a snapshot to a 4.2
system from a 4.1 system.


Action Taken:  Told customer that you cannot use a snapshot from 4.1
on 4.2.  He can however syncronize from a 4.1 system to a 4.2 system.
