Replicate failure, 2.0.11 to 2.2.3 upgrade

[nicholas geovanis]

Hi to all -
I'm upgrading a cobbler server running cobbler 2.0.11 on CentOS 6.0,
installing fresh on a new machine running RedHat 6.1and cobbler 2.2.3. The
new install (cobbler from EPEL RPMs) is uneventful, "cobbler check"
indicates nothing suspicious-looking.

After initial configuration and check that cobblerd and httpd start-up OK,
I thought I would take the wiki recommendation and attempt a "cobbler
replicate". Verified rsync connectivity between the hosts. Result is the
"internal error" below. Wondering if I've missed something simple.
Thanks......Nick Geo

Sorry, replication between different versions is not supported. Your best
bet is to manually rsync the /var/lib/cobbler and /var/www/cobbler
directories over to the new server and restart cobblerd once that's
complete.

I saw no mention in the doc that replication across versions wasn't
supported, but I might have missed it. And I was thinking about just
copying the files over and hoping for the best, but I wasn't sure that was
recommended or supported. Looks like it is? Bravo and thanks....Nick
