I have been using Delta Chat as an AppImage, but it does not update itself, so I thought it better to use Snap. I installed the same version as Snap, but when I run it, it does not recognise the existing profile. I tried doing a symlink:
export backup from appimage, then import backup from snap.
or copy.move over the accounts folder and config.json file (or the whole DeltaChat folder if you want to migrate everything including local storage of webxdc apps and chat background image.
that means you try to start two instances at the same time. Or the lock file still exists somewhere, maybe restart the computer.
No it’s inside of chats and media. Or if you find a way to have both installations open at the same time: then you can also try to use setup second device and copy the qr code to clipboard.
