We have a bit of a (overly) complex setup. We have 3 load balanced Matomo web front end servers for tracking requests that are feeding into Redis. We also have 1 Matomo Web server for running reports and viewing data, and 1 more Matomo server for performing the report archiving. All 5 servers are pointing to 1 database.
The question is, what is the recommended best practice for upgrading this setup to a new version of Matomo? Right now our process is to download and package the upgrade separately, and then copy it to all the servers manually. But that’s very inefficient and I’m concerned we either miss some aspect of the upgrade (on the DB, for instance) or overwrite something we don’t want to. We tried logging in to each server and using the built in Upgrade functionality, but after the first server was upgraded we received the DB/Web mismatch error on subsequent servers.
So what is the recommended approach? How have others handled this?
Thanks a lot.
