upgrade ConFluence from 7.0 to 7.3 assistance please

Question

We have a user count of < 5 users on 7.0 and an H2 database. I can export the database content easily, that is our occasional backup. H2 works for us and we prefer to remain on H2, based on  our current needs.

Question: Is there a clear understandable step-by-step process that I can use to just upgrade to 7.3+ , using the download TGZ or the eval version and update the production  license? This also would allow us to keep the H2 database until there is time to migrate and capacity requirements to migrate to another external database.

Ubuntu 18.04.4+  server with gnome GUI. openjdk-8, Atlassian Confluence 7.0.2 + hsql

Sincerely,wm

Thank you. I have used that technique before and it worked. I was being cautious as the documents say "upgrade database first". This is really not necessary for our requirements, I will use this technique  and see how it works. Thank you.

You can also do a new installation and then restore a backup version of the previous installation.

After the reinstallation, Confluence ask whether a backup should be imported.

Why don't you use the downlaod Linux 64 bit, which has an installer for the command line. This detects an already installed version of Confluence and also automatically takes over the H2 database and its content.
