I upgraded my production MM 2.0.13 to MM 2.1 (and later that to 2.1.1) by
installing over the old installation without any problems. The machine
concerned supports over 460 lists, some with archives and some without, and
conversion was a non-event; only a 20 minute interruption in service. I did
set up a few scripts using $prefix/bin/withlist and base on
$prefix/bin/fix_url.py to sort out some of the list attributes that were
not to my liking after the upgrade.
Just make sure you read the install and upgrade notes thoroughly and watch
out for potential problems if you have used things like patch #413752 on
your MM 2.0.x installation.
I confess I cheat by doing test runs: I installed MM 2.0.13 with all the
patches I was using on my production MM 2.0.13 system onto my secondary
server, added some sample lists and then did a trial upgrade to MM 2.1
(initially beta). Repeated this until upgrading the test system was
completely trouble free; then doing the real thing was a non-event. Doing
this was where I sorted out the fixup scripts I needed, and found the sting
in the tail of patch #413752 and developed patch #651406 to fix it (which
btw works OK with MM 2.1 and 2.1.1 source).
I started using this test upgrade approach when I first upgraded from MM
2.0.3 and have stuck with it ever since. Train hard, fight easy!
