Updating or Patching

[Nizer]

I've got a 1.1.14 installed and have had the forum for years. Can I update or patch right over top of the old forum and be running the 2.0? Has this been done before or was it intended to upgrade in this manner? 

I'm only asking because I know I have zero mods I want to save and all the permissions and whatnot I would love to save for 2.0. Is this possible? Is there a link for "patching"? All I see is the upgrades and info.

TYVM in advance,
ReZ
