 # Upgrading
-Because of updates to the database structure, users who upgrade from a commit BEFORE [d5bcbe8fb79e80f9d603b764ac787295cceffa34](https://github.com/syzoj/syzoj/commit/d5bcbe8fb79e80f9d603b764ac787295cceffa34) (Feb 21, 2018) **MUST** perform the following SQL on the database.

Judge server must be upgraded together, and `daemon-config.json`'s  `ServerUrl` and `ServerToken` (= `judge_token`) must be filled. If judge and web run on different server, it's recommend to move RabbitMQ to judge server.
