@jdaviescoates This is an idea I have quickly considered as well but one reason why I want to move this installation to Cloudron so desperately is that I want to have less work with it, not more 🙂
We will probably need to live with the fact that we will need to re-share all information again and simply do the move using one of the manual ways (e.g. user migration plugin). That will create chaos for a day or two, but at least then we will have a more stable installation.
