Due to the unfortunate down-time of slrpnk.net we are currently researching possible blockers for creating a Lemmy to Piefed migration guide or script for a relaunch in 1-2 months.
I have never done such a migration before, but generally it seems possible, although migrating image uploads from Pict-rs adds additional complexity (that might not be worth it).
I have created an issue on Codeberg about possible blockers here, but additional input on possible issues or examples of similar migration scripts would be appreciated.
If anyone else has similar plans, please let me know so that we can work together on this.
I would need to check at database level, but I guess on the subscribing side it is only a list of communities to display? The real “work” for subscriptions happens on the remote instance to decide with activities to send.
But that indeed raises the interesting point on how to retain subscriptions of remote users. Anyone got an idea how that is handled on database level? Is it just the same list but for the non-local users that are mirrored in the database?
