Hi Ryan,
I don't see why it wouldn't be possible.
Copy the otrs directory elsewhere, edit the config (otrs location, database details) edit apache config....
Thanks for the reply, are you suggesting copying the whole of the otrs installation directory? The problem is I'd want just one copy of the binaries/libraries on the server (to make patches/upgrades easier), but individual config files (and perhaps databases) for each virtual site. I'm quite happy with sorting out the Apache config for multiple OTRS installs, the question is whether it's possible to have OTRS config files decoupled from just the one OTRS installation, and then how to direct Apache to these configs. I had a thought that perhaps this could be done with symbolic links for the binaries/libraries, so that it appears that there are individual complete installs of OTRS on the machine, when in fact they share the same binaries/libraries. But this seems messy, and doen't really fix the problem properly as future upgrades/patches would require maintenance of all the symbolic links for each virtual site. Gary
