[xwiki-users] upgrade to 4.4.1 from 4.3

I upgraded from 4.3 by upgrading (replacing the 4.3 .war contents with the 4.4.1.war contents) /webapps When I restarted tomcat, and connected, it then ran the automated extension upgrader When I look in the extension manager, I see 51 extensions, ~half of which are version 4.3 If I try to uninstall any of the 4.3 versions, they show the 4.4.1 version as a dependency. I'm confused...
