I recently upgraded from a 1.1 milestone to 1.6.0 in one fell swoop. I did an export from my old installation, installed the new version in a separate location, tweaked the out-of-the-box config (I kept notes on what I customized last time so I could re-do it) and then did a selective import. I did have some troubles. My exported XAR was huge and the 1.6.0 VM kept running out of heap on import. I ended up excluding history (*sniff*) and also manually deleting unwanted items from the XAR, as well as increasing the heap size. But in the end, it worked! Regards, Brian.

Should I attempt an upgrade all the way to 1.6.1 in one fell swoop or should I upgrade to 1.3.2 -> 1.4.1 ...etc. Do I need to upgrade the XAR for every release or just once? I am using hsqldb as my database, but after getting everything upgraded correctly, I will be moving the database to MySQL. I have searched the archives but I haven't found anything more recent and also dealing with wide range of upgrading I need to do.
