Sorry if this is covered elsewhere, I've run a few searches but other threads seem to deal with installing while upgrading etc.
So here's my situation.
Currently running 3.0.4 with a few mods :
Private message at 1st login
User connection logging.
The site has around 2000 posts & just under 200 MB of uploaded attachments. Also because of past upgrades from 2.X the table names do not have the standard prefix - is that an issue ?
Given that none of the mods I have are especially complex to reinstall the simplest method would seem to be to backup the existing files. Install all files from the root directory of the premod over the existing ones (expect config). From this point I'm not 100 % clear on the process so would welcome some advice on the steps to follow.
