I just tried an upgrade from 3.6.4 to 3.9.1 and it did break. Java Heap error. I tried increasing the amount of java memory without success. It was also using a lot of CPU (trying to upgrade the database?) I even tried copying the embedded-db onto a newliy installed working 3.9.1 with the same results. ie incompatibly database. Fortunately I still had the installer for 3.6.4 and installed back over the upgrade version and it all came back. I still dont have a way to export the users to the new version as the user-export-import plugin wont run on the old version.
