Some steps I collected during our last upgrade; not definitive cookbook, but it worked for us:
1) If possible (and you haven't done so already), move your OTRS server to a virtual machine, preferably VMWare-based. Makes cloning in the future a lot easier. 2) Build a new VM image, and install all the patches/OS stuff 3) Install the new version of OTRS on the new VM image and make sure it has all the prereqs. 4) Schedule an outage of the old OTRS server, shut it down and take a backup of the database. 5) Import the database backup into the new OTRS machine 6) Run the migration scripts on the new OTRS machine. Fix any errors and note what you did. 7) Test and tweak the new OTRS machine to make sure any customizations you did still work. Note what you did. 8) Schedule another outage of the old OTRS and take another database backup 9) Drop the test DB, and import the new backup to the new server 10) Run the migration scripts again, and use your notes from #6 to complete the import. 11) Apply tweaks from #7 12) Swap IP addresses for old and new OTRS servers 13) Declare victory and march home. In the future, you can take a snapshot of the running OTRS server and test the upgrade from that snapshot. Steps 6 and 7 are really critical because you have to do the steps twice. Take good notes (in fact, if you use the ITSM add on, use the change request doc to note them, and you'll have good docs for the local tweaks for next time).
