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…

I’m no expert, but is there any conflicting nginx stuff or outdated redirects in your app.yml?

I mean, the discourse folder is a direct copy from what used to work. I recognize that it’s a different server, resources, versions of docker, etc. I’m assuming most of that should be abstracted away into the docker container where the only real difference between the two env is docker and resource…

I’d like to keep the data. As of now I simply copied the entire data in /var/discourse which includes all the data. Postgres, Redis and so on.

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.
