I am preparing an upgrade from WPMu 2.9.2 to WP 3.0 and I am pretty confident I have all my plugins and themes in order, but I have a question about the multi-database plugin SharDB. Anyone test this out on a WP 3.0 version with multiple netowrks (and by multiple network I mean several different domains with their own subdomain sites running off one install).
I was ready to upgrade, but was told that SharDB may not work with multiple networks and wanted to check hear and see if anyone has and ideas on this one.
For the multi-network setup I am still using David Dean's Multi-Site plugin for this setup. And it works on a WP 3.0 site I upgraded with a single database, but worried it may break on a setup with multiple databases.
