Re: [xwiki-users] Upgrading XWiki Enterprise From 1.2.2 to 1.6.1

Greetings- I am need to upgrade an installation of XWiki from 1.2.2 to the latest (currently 1.6.1) and I am trying to put together an attack plan. 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.
