Migrating from OwnCloud 9.1.3 to 10.16.0/MariaDB 5.5 to 10.11/CentOS 7.9 to Rocky 10.1

I’m working on migrating my OwnCloud and I’m having many issues.

Original Instance Info:

  • CentOS 7.9
  • OwnCloud 9.1.3
  • MariaDB 5.5.68-1

New Instance Info:

  • Rocky Linux 10.1
  • OwnCloud 10.16.0
  • MariaDB 10.11.11-1

I was able to migrate the schema from MariaDB 5.5 to 10.11 after some research. I was then able to install and configure the newer version of OwnCloud on the new server. The OwnCloud migration instructions indicate that I should just be able to dump the old data and import it into the new MariaDB instance. After I do that, I stop and restart the MariaDB & Apache HTTPD servers. When I reload the web page to log into OwnCloud, it indicates that there are incompatibilities with the data.

What is it that I need to do to migrate my data from the old server to the new one. Thanks for any pointers and assistance.
