Upgrading roundcube v6 to latest version
I installed roundcubemail on my ispconfig server back when it was at v6. Now after a bunch of ispconfig3 updates, I am having issues with password changes, autoreply and forwarding rules, giving me soap errors like "login_error_regex". Now I found a thread that said to add a line in the ispconf3_pass.php script and that worked. But I don't really want to spend hours trying to debug every other script for those errors when an upgrade may solve everything.
My question is how do I actually upgrade the roundcube and it's plugins without blowing up my current running system (expecting that rouncubemail access is off during the upgrade). There seems to be many different "versions" of how to upgrade, and I'm a little confused as to which is the best.
Thanks in advanced,
