Upgrade with a few curveballs...
 

Thanks in advance for any help* advice* etc that can be given!

I am currently running VBulletin 3.6.4 and want to upgrade to the newest version* 3.8.4. I have read through the update instructions but was unsure what conflicts this might cause with some of the other stuff we have running on our site:

Mechanical Fluid Theme
vB Advanced CMPS v2.2.0
Subdreamer 2.5.3.2


We use Subdreamer for the content management of the site itself* and it uses the vB database. Am I OK updating exactly as the instructions state or are their extra steps involved considering the other stuff I have running?

I am a bit of a newb at this stuff* so any help is tremendously appreciated.
