Upgraded to 0.4.0 on Server Pure without issue. Was running Nextcloud (legacy) on prior install, have a backup. Upgraded to Start9 registry version of Nextcloud 33 - able to log in but database not populated with files from prior version. Is there any way to use the pre 0.4.0 Start9 backup of Nextcloud to populate the current Nextcloud version?
If you carefully follow the instructions for updating to 040, all the files in your Nextcloud should have been migrated without any problem.
