I was wondering if anyone has a how-to or a list of steps to follow when migrating OTRS from Windows to Linux.  I've tried once unsuccessfully.  I've currently got a working OTRS 2.2.6 system running on windows.  It was installed with the win32 installer available on www.otrs.org.  My target system is Ubuntu 8.04.   I'm no linux expert but I can figure out enough to get myself in trouble.

On my first attempt, I installed mysql-server, mysql-client, and otrs2_2.0.4p01-18_all.deb.  Then I copied all the var/articles over, copied the entire contents of the mysql/data folders (yes this is probably a bad idea, but since the machine is dedicated to otrs I didn't see any need to preserve anything), and the kernel/config.pm and kernel/config folder.  Then I manually edited config.pm to change the "c:\" paths to /usr/share/otrs.  After restarting mysql, I was able to access the otrs database with the otrs account and password without a problem, but I started getting file-system permission errors trying to access /var/lib/otrs/article when i fired up otrs... this is where I started getting confused, because the application runs in apache2 as www-data but the files and directories are all owned by otrs:www-data.. it seemed to me that it ought to be running with suexec as otrs, but that was beyond the scope of my understanding.  Instead I tried granting www-data write permission to the var/articles directories.  That got around the permission problem, and I'm able to reach the otrs logon page but it wont accept my credentials. 

I think I just totally borked this entire setup so I think I need to start fresh with some step by step documentation.  If anyone can provide some assistance or some step by step instructions I would greatly appreciate it!

Thanks
