GNUsocial Migration Script
Posted on 2016-11-25 (Updated on 2016-11-29)
Update: Tobias provided a canonical link to his StatusNet Move Account script.
When you're migrating to a new GNUsocial instance, it's handy to be able to set up your subscriptions from your old account on your new instance. Tobias Diekershoff created a very helpful Python 3 script to help you migrate those subscriptions!
I couldn't find any place that Tobias had posted it, so I'll just paste it here for posterity. I made some slight modifications to represent the change from StatusNet to GNUsocial.

"""
With this Python3 script you can selectively copy your subscriptions from one
GNUsocial [1] instance to another. The script runs in the terminal and does not
need any command line parameters. All you need to do is change the credentials
for the two GNUsocial instances (see below) and answer some yes/no questions.
If you encounter any problems feel free to contact me [2] or patch them by
yourself.
Have fun!
