The old syntax works unless have a colon in your snapshot names.  In that case, the \
portion before the first colon will be interpreted as a fileset name.  So if you use \
RFC 3339/ISO 8601 date/times, that?s a problem:

The syntax for creating and deleting snapshots goes from this:

mm{cr|del}snapshot fs100 SNAP at 2016-07-31T13:00:07Z ?j 1000466

to this:

mm{cr|del}snapshot fs100 1000466:SNAP at 2016-07-31T13:00:07Z

If you are dealing with filesystem level snapshots then you just need a leading \
colon:

mm{cr|del}snapshot fs100 :SNAP at 2016-07-31T13:00:07Z

Thx
Paul

I think at least the most popular old forms still work, even if the documentation and \
usage messages were scrubbed. So generally, for example, neither your scripts nor \
your fingers will break. ;-)

Why was mmdelsnapshot (and possibly other snapshot related commands) changed from:

Mmdelsnapshot device snapshotname ?j filesetname

TO

Mmdelsnapshot device filesetname:snapshotname

..between 4.2.0 and 4.2.1?

It?s mildly irritating to say the least!
