Today, US based file sync & share vendor Kiteworks announced their acquisition of ownCloud and Dracoon. Nextcloud offers a free hands on migration service and takes over the remaining runtime of the contracts. Migration is a very quick and easy process, as shown by the many hundreds that have done this already over the last years.
BTW, could you do with another mod? Because besides you (and Ruud), the mod team is pretty much AFK.
