When upgrading to a new release of Sync (currently running 1.4.93 Beta), I lose all my set up, no sync folders are listed in the web UI. I guess the configs are in the hidden .sync folder (below the folder containing the executable), but is it safe simply to copy the contents of .sync to the newly installed release? Should I also copy the SQLite databases and associated files (3 files per symc'd folder)? (I'm running Linux Mint 17 Xfce)
