Thanks, Coralie.
Yes, I feel it's important that we stand and act on what we believe in.
Toots can be backed up and exported (along with all the media), it is an option in the Preferences panel.
But importing them, I don't think it's doable at this time.
The best option is to leave all as is, have a full backup and create pointers to a new location if a move is needed.
There's an option in there regarding a Move, but I imagine it would lock the local account, no longer posting possible, that is not ideal.
I would like to see some action, and just making it clear how important that is to me.
I have a feeling that you are right -- although in the Preferences panel there's this :
https://qoto.org/settings/export
...and the text is "The exported data will be in the ActivityPub format, readable by any compliant software."
I don't think the head developer of mastodon wants the functionality of people's data coming along with them, and importable as needed.
Would be nice to know for sure, if there's some viewer at least we could use to access this.
