Curious about upgrade path

[محروم.كوم]

Greetings everyone and vb team.

I am excited about the VB4 release and have been taking steps to prep my site for the upgrade.
I realize that many "mods" will no longer work and most are probably no longer neccessary anyways*
so I have been uninstalling the majority of stuff and "toys" my users have enjoyed.

I have wittled my uninstall down to a few major mods.

vbGallery* vbOptimizer* vbAdvanced* and IBProArcade.

I don't expect any support for those mods here* but I am curious if I can successfully upgrade my site to vb4 without uninstalling those mods.
I don't have a problem getting rid of the ash-and-trash* but I would like to leave those "installed" per se so when those developers upgrade the scripts* I will be ready to go.

Not to mention the database of games and pictures and such.

So essentually I guess I am asking...

Will the vb4 upgrade process if you have some mods still installed?
I realize those mods won't work and that's fine* I just don't want to loose the data so it can be used when those mods are updated.

Thanks for your time and work __DEFINE_LIKE_SHARE__
