I want to upgrade to 3.8.6 but worry it'll overwrite my old files!!

[Mostjolly]

Okay, my current board is 3.8.2 and I'm planning to upgrade to the latest 3.8.6. PL1, will upgrading to this newer version overwrites my custom skin codes in templates and my global phrases?

Your response would be appreciated,

It won't make any drastic changes but ill try on a test board first. Depends on how customized your skin is.

PS Say hi to cory for me.

It won't over-write your custom templates but you may need to revert some before things will work right... off hand the only change I know of is to the 'mark all threds read' function which you can manually fix without reverting your templates but 3.8.2 was a long time ago, I don't know for sure that's the only change. You can probably find old threads on vbulletin.com on required template reverts (if any) between all the versions.

it'll not effect anything, just after upgrading it'll show you how many temples are new in this version,
now its upto you if you want to keep the old modifications or no,

it'll not cause anything
