3. You will lose your theme, its customizations, and all addons.


Basically: you will have to re-do your theme, customizations, and find similar addons. You would probably have to purchase a lot of them, since XenForo addon developers are only interested in selling the licenses. You will find some free ones, but mostly, you will have to pay.

I would advise anyone who is running vB3 and vB4 to update as soon as possible. Not only because it runs very old PHP, but because it's not mobile compatible.

Forums are damn hard to run as is, and the fact that it won't work properly on mobiles is a huge caveat, and probably makes you lose a decent chunk of users.

If either you or AmeliaG need any help, feel free to PM.
