I am moving my discourse installation to a new server, DNS etc is all already patched up, valid SSL certificates on the server I copied the /var/discourse folder from server A to server B and trying to rebuild it but i’m having some issues. I looked at the install notes which recommend The default…

I’m not sure this is the root of your issue, but I believe that after moving to a server with different specs, it’s advised to run ./discourse-setup again so it can configure some stuff accordingly to the new specs (swap, shared buffers, unicorn workers…). Experts will correct me if I’m wrong …

Interesting, that would be unexpected but I’ll give that a go and see. Okay – Update: Running the setup didn’t change anything. I simply prompted me for the host and adjusted some minor settings. So far still no go. Same error on rebuild. I also tried running the doctor to no avail. The setup…

Are you running Discourse in Docker as recommended or directly on the server?

I strongly recommend following the official community’s tutorial on migrating servers rather than directly copying the /var/discourse folder.

Yes, docker pattern. Hence the issue rebuilding the container comments.

Do you have a reference to that doc? I thought this worked last time, so I’m surprised at how much trouble this is giving me this time around.

Your installation of a fresh Discourse instance on your new server, followed by the restoration of your backup, will ensure everything operates seamlessly. I have followed this method, adhering to the official guidelines, to migrate servers at least five times without encountering any issues.
