I’v read numerous topics and threads on the web about how to migrate from owncloud 9 (or sometimes 8 ) to Nextcloud.
My problem is: to install Owncloud on my Raspbian, I used the package manager which bundles a 7.0.4 version of Owncloud.
Is there a procedure to migrate from that old version to a recent version of Nextcloud ?
If not, can someone give me advice about the way to achieve a migration of the data, configuration, passwords etc ? My priority (of course) is to loose no data or user configuration.
Thanks in advance,
