Starting an Installation at Least Once

To ensure an installation has been started at least once you must:

  1. Ensure all databases have been upgraded with the version you are trying to run.

  2. Ensure at least one of the Management Servers has been upgraded, however if you choose to only update one you should leave the other server deactivated.

  3. Ensure all database servers are running.

  4. Ensure the UI application is upgraded.

  5. Start one or more Management Servers and ensure it starts correctly.

  6. Verify that the system has started correctly by logging in through the client UI.

    1. Optionally you can also check the Management Server logs to ensure the upgrade did not generate any errors.

  7. Assuming everything has started correctly and the log showed no errors, you can stop all services and upgrade to the next version.

This release includes version 4.4 of the MongoDb database server. This version requires the Visual Studio C++ 2019 x64 redistributable library. Technically this has been part of the Witness pre-requisites since the release of 4.11, however we recommend this is checked before installing Build 1099.
