[otrs] migrating otrs 2.0.4 to linux from windows

Hi all,its been a while since I posted here(that's a good thing cuz OTRS has been working without issues for a year and a half!). I was contemplating migrating our current version and settings of OTRS to a linux box from windows(mysql db is not on the OTRS webserver). Depending on how hard this will be I think we would like to go that route, and then eventually upgrade to the latest and greatest version of OTRS. I was wondering if anyone could shed any light on this or at least point me in the right direction. Thanks in advance. -Isaac G
