Hello, I'll clarify this in the upgrade docs, however you may overwrite all files (except the configs), because there hasn't been any incompatible change.
As a precaution, always backup your config files and especially the encryption key.

After reading upgrade instructions i found nothing regarding version 1.3.7. As i want to do an upgraade of piler form the first time i need some hints to do this. It is clear that making a backup of all configs is recommended. Can i copy over all files? Thanks for your advice Regards BKH
