+## Troubleshooting
+
+### Server version mismatch
+
+**Problem**

+The generating dump step failed with this message:
+
+```bash
+2025-11-12 09:54:54 ERROR: Generating the dump of your database has failed. The 'pg_dump' command has failed with the following output:
+ pg_dump: error: aborting because of server version mismatch
+pg_dump: detail: server version: 16.9; pg_dump version: 15.12 (Debian 15.12-0+deb12u2)
+```
+

+
+Ensure that the local postgres server does not have a never version than the remote server.
+
+If necessary downgrade the local postgres server.
