Hi, I’m going to upgrade my Temporal from 1.15 to 1.16, the current database scheme version is Postgre 1.7 In the guide link [Release v1.16.0 · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/releases/tag/v1.16.0), database scheme version needs to be Postgre 1.8 The document said: “Use the Schema Upgrade Tool to upgrade your schema version. How to use the Schema Upgrade Tool: [https://docs.temporal.io/docs/server/versions-and-dependencies/#upgrade-your-version-of-temporal.](https://docs.temporal.io/docs/server/versions-and-dependencies/#upgrade-your-version-of-temporal.)” Howerver, the above link is broken. Could I know where the Shema Upgrade Tool is? Many thanks for your help! ---

Schema tools are [here](https://github.com/temporalio/temporal/tree/master/tools), you can build them by running “make” in the main temporal github repo. I believe the doc link should be [Temporal Cluster deployment guide | Temporal Documentation](https://docs.temporal.io/cluster-deployment-guide/#upgrade-server-version) Hope this helps.
