Buddypress 1.2 No site wide posts, caused by multi db?

Just upgraded to Buddypress 1.2 and wpmu 2.9.2

Tested it on a test server with an identical setup except for Multi-db plugin.

Now i've upgraded and my activity feed and recent site wide posts are not working.

Everything is pointing to Multi-db, which I haven't upgraded yet.

Tried to upgrade the db.php only as its the only one that seems to have changes.

After the upgrade I couldnt post updates in the activity feed at all.

What's the process of upgrading the Multi-db plugin?

I have Version: 2.8.5
