Hi DryHeat,

I always do a clean install to a separate partition rather than doing an "in-place" upgrade. Before doing this, I first make full backups (I use tar, personally) of non-recording partitions. If you haven't done this before, you'll probably need to do some re-partitioning to make room for a clean install, which is another reason to make good backups first. The reason to have a new, separate partition is so you can go back and forth to and from your current working environment and the new environment. Especially with the change from SD-DD (schedules direct-direct data) to SD-JSON (schedules direct-json). It took me more than an afternoon to get that sorted out to my liking, so it was important to reboot back to the known working environment. I also do this back & forth to upgrade my remote front ends, too.
