  • Root cause: Certificate issue with the K2 Configuration Service.

Steps to Resolve:

  1. Validate and Repair Certificates:

    • Navigate to the K2 installation media's Installation folder.
    • Run CertificateManager.exe.
    • Type "v" and press Enter to validate certificates.
    • If errors are found, type "r" and press Enter to repair certificates.
    • Exit the CertificateManager.exe.

  2. Relaunch Setup:

    • Run Setup.exe again.
    • Perform the "Recover" step.

Additional Considerations:

  • If issues persist, consult K2 documentation or contact K2 support for further guidance.
  • Thoroughly review related KB articles or community discussions for potential solutions.

Key Points:

  • The K2 Configuration Service relies on certificates for secure communication.
  • Validating and repairing certificates using CertificateManager.exe can often resolve migration errors.
  • The "Recover" step in Setup.exe addresses issues related to certificates.
