[otrs] Ticketnumber reset after migration

Hello, I moved my OTRS 2.0.4 install from a Fedora Core 2 to a CentOS 4.2 box yesterday. Installed a fresh 2.0.4 on the new server, stopped the otrs service on the old one, dumped the db and recreated it on the new server. I also copied Kernel/Config.pm over and started the otrs service on the new server. Seems to work just fine, except for the fact that new tickets get ticketnumbers starting at 100001 again, while we've set the ticketnumber length to 5 digits and already have a lot of tickets in the system. Where should I look to fix this and go on from where we left? Thanks, Nils Breunese.
