Migrating from Mastodon to Pleroma
Mastodon bad. Pleroma good.
If you’ve been following me on the fediverse, you would’ve witnessed my numerous (failed) attempts at migrating from Mastodon to Pleroma, running on my Raspberry Pi. I finally got it working, and these are the steps I took. It’s sort of a loose guide you could follow, but I can’t promise it’ll work for you.
The Erlang and Elixir packages are pretty broken and outdated on
Raspbian. So this time, I built them from source.12 I also assume
you have Mastodon and Pleroma (source, not OTP) installed—probably at
Once you have Erlang and Elixir compiled and sitting in your
Now read the readme and the
do_migration.sh script to get an idea of
what you’re getting into.
Move into the cloned directory and create a
$ yarn # install deps $ cp -r mastodon/* /home/mastodon/live $ cp -r pleroma/* /opt/pleroma $ RAILS_ENV=production yarn masto export
If you run into any permissions issues,
chown and proceed. This should
export all your Mastodon activity into
Now, copy the
migrator directory into your Pleroma installation path.
$ cp -r migrator /opt/pleroma
You can then import all of it into Pleroma (possibly prefixed with
$ MIX_ENV=prod mix migrator.import
If all went well, you would’ve successfully migrated from Mastodon to Pleroma. If not, well feel free to send me an email (or @ me on the fedi). I suppose you could also reach Alex—he’s the incredibly based guy who wrote the migrator, soapbox-fe and does some Elixir magic he keeps posting about.
Rest assured, the migrator has a 100% success rate—Alex and I are apparently the only two who have it working. 2/2.
