Upgrading Primary and Secondary GoCD Servers using Business Continuity

Assumption: You already have an existing Business Continuity Setup, as explained in our documentation here

1. Shutdown down both the Primary and Secondary GoCD server.

2. Perform server upgrade by following our documentation here for both primary and secondary server individually. This step will run database migrations and also perform a server upgrade.

3. If you are upgrading from any GoCD version before v18.8.0, please note GoCD server from v18.8.0 is no longer an auth provider. You will have to include business-continuity-token file in the config directory on both primary and secondary and restart the individual servers.

   The content for the business-continuity-token file is a Business Continuity token which can be of the following form

       #business-continuity-token
       user = password
       OR 
       user:password
   

   Note: The Business Continuity token passed in the token file (business-continuity-token) is only used for Business Continuity sync and log in and is independent of any existing roles configured within GoCD using any authentication/authorization plugins.

   Note: You must set up the secondary server as standby to avoid any database corruption. Please look at our documentation for the same.

4. Once you have the above setup you should be able to navigate to https://<sec-server>:<port>/go/add-on/business-continuity/admin/dashboard and see the status of the Business Continuity.
