I'm not sure if this has been asked before* but I cannot seem to find anything about it.
I know most* if not all of my current modiications will cease to function under vBulletin 4.0* therefore what would be the best practical way of upgrading. If I uninstall them I will lose data from them* or do I just disable the lot using vB 4.0 own config.php file* before upgrading? Or will this way change as well?
Surely* the update will still carry modification data from database tables directly to vBulletin 4.0?
I gather many people will be in the same predicament as myself when we actually get to this stage* therefore I wanted to know beforehand - if possible.
