      Issue Summary

      Opening base URL multiple times during Data Center migration will break the migration process.

      Steps to Reproduce

      1. Open multiple tabs to point to the same URL of Confluence.
      2. Install Confluence as Server.
      3. In the Administration > Licensing switch the license to DC license.
      4. Restart Confluence instance
      5. During the startup, confluence will go into the migration process.
      6. After setting up network cluster parameters, you will have few minutes while the migration is still running
      7. Open other tabs and try to open Confluence base URL a few times.

      Expected Results

      Nothing will happen, and you will see a blank page that is trying to load.

      Actual Results

      You will receive error 500 without any stack trace in the browser:

      But from the side of the logs, you will see this error:

      Workaround
      

      Make sure that nothing can reach your Confluence instance at the time, like load balancer health checks from AWS, users, or different tabs that are targeting Confluence instance.
      
Changing the server.xml connector port temporarily can also help to finish migration uninterrupted.
