Migrate Config Files
config/authentication.yml has a new structure with a different section for each rails environment. Edit your authentication particulars to incorporate this new structure. An example is found in config/authentication.yml.example.
Dump r5 database (mysql on pawpaw)
Load to r6 database (sqlite locally)
Sqllite3 doesn't like mysql dump files so a transformation script needs to be run on it. Download https://raw.githubusercontent.com/dumblob/mysql2sqlite/master/mysql2sqlite, make it executable, and run it on the dump file.
This returns "memory" which is good.
In rails console, you might need to remove the cached role maps.
