Upgrading from 3.6 to 3.8 help...

[kronnos]

Hi,

I want to upgrade and move servers at the same time. I have never done an upgrade before from 2 different versions so it is new to me. I have read the upgrade instructions but there are still things I have a problem with.

1: When moving 2 a new server, without doing any upgrade or changes what so ever... I know there are still thinsg I would need to change to make it work. What files do I need to change (for exp: htaccess, or point to new server location).

2: When upgrading, im sure that most of my mods will not work with the new version or at least I would need to upgrade those mods to be compatible. Because of this I would probably need to make a clean install of VBulletin and then add all the mods I would need. On the other hand If I remove all the mods and do a clean install I would still not be able to just keep the clean database because ti will have data of mods I used. How do I check for the original VB database files and the ones from the mods just so I copy them separetly and then add them when I upgrade the mods? For example, I would want to keep the Itrader records and probably other things.

Any info on any of the above or whatsoever regarding upgrading or backing up the database? Any information will be helpfull that will get me a better and error prof upgrade like ways to do it or software to use.

Thank You!
