frold is attempting to restore a Discourse backup from an old server to a new one but encounters an error: “You’re trying to restore a more recent version of the schema. You should migrate first!” Despite both servers appearing to run the same Discourse version, itsbhanusharma clarifies they are on different commits of beta10, advising to rebuild the new server. frold rebuilds using ./launcher rebuild app but the error persists. itsbhanusharma confirms the host OS (Ubuntu 18.04 vs 22.04) is irrelevant. Finally, RGJ suggests the issue stems from a missing plugin — specifically, the discourse-chat plugin — which introduces schema changes not present in the new server’s core. Installing the plugin before restoring should resolve the migration conflict.
Im trying to move from one server to a new server.
The are having the same edition of discourse:
I get this error

Why the migration error? Why two different versions? They should use the same…
