Do you have to totally rebuild MST to apply an upgrade?

• A. Yes, a full rebuild is required
• B. No, you can apply an upgrade directly to your existing MST build without rebuilding the entire environment
• C. Only if upgrading from a major version
• D. It is not possible to upgrade MST

Answer: (B)

Upgrading in place is common. The idea is that you can apply an upgrade to the existing MST installation without tearing everything down and rebuilding from scratch. This approach updates the necessary binaries and data structures while preserving your current configurations and content, which minimizes downtime and preserves work already set up in the environment. Of course, you should verify compatibility, read the upgrade notes, and back up before proceeding, because some upgrades may require additional steps or migrations. The key point is that, in many cases, you don’t need a full rebuild to apply an upgrade, which is why upgrading directly to the newer version is the best choice here.
