Migrating From Fenix 2 to 3
Starting with version 3.0.0-rc.4, Fenix is self-updating and has a built-in migration utility.
There is an older online migration wizard, which was built for development and early testing. We do not recommend using this for migration purposes (use the built-in one instead), but it can be used if Fenix 2 was not installed in a standard manner. Some users have found this utility useful for creating a manual backup of the Fenix 2 "servers.fnx" file (a JSON file containing all of the servers in Fenix 2).
There is no update utility for Fenix 1 (unsupported).
