I am trialing updating from version 17, the first time round I did each version individually, ran the upgrade script / occ each time and worked my way up, second time around I have just jumped straight to the latest version and done a file rescan.
My files seem accessible, nothing looks obviously broken, is there anything lurking that could catch me out?
You can make a backup of the files, install a fresh new Nextcloud version e.g. Nextcloud 27 and then make a
occ files:scan --all that Nextcloud knows all your files. But all other data e.g. shares are gone. For pure data storage, however, this can be a useful method.
Thankyou for your fast response much appreciated for the answer.
just wanted to note that shared things from another user still seem to be working okay
