BuddyPress upgrades with Multi-DB

Regarding Comment:

Has anyone had experience with upgrading to BP 1.2 with multiDB installed?

I'm getting the following in my logs:
WordPress database error: [Table 'wp_bp_groups_members' already exists]
CREATE TABLE wp_bp_groups_members (....

I think I'm getting one for every table it tries to update.

Does anyone have suggestions for doing the upgrade?
