Hi! Is it possible to upgrade owncloud 10 to owncloud Infinite Scale 2.0 without data loss? How can I do this, is there an update instruction?
There is no direct migration path. You would need to set up a new system with Infinitescale in parallel and migrate the data user by user as described in Migrate Data using rclone | ownCloud
Keep in mind that Infinitescale may not yet have a replacement for oC 10 apps. I would recommend testing Infinitescale first to see if it meets your needs before you start migrating data.
Can I clarify the next version of ownCloud 10.12 will be available only in docker?
