Hi,

I just recently (2 weeks ago) converted an mvs server to version 2.  What I
did was
essentially to issue the DISABLE command.  This prevents client-nodes from
logging on but administrators can still access the server.  Then I used
dfdss to dump all the adsm datasets to tape.  I then dumped the server with
the adsm dump db consistent=yes parm.

By the way, if you use consistent=yes this WILL quiesce any activity on the
server and will ensure that you have an intact database dump.

After the adsm dumpdb was done I shut the server down, renamed the startup
procs, put the upgrade parm in the proc and let 'er rip.  Everything went
fine.  The only caution I would suggest is to prevent folks from migrating
right away.  In the event that you do have to fallback to version one you
might lose migrated data.

Hope this helps,
Dave.
