There is no upgrade path to VMware BMA 3.1. This is due to some major internal architecture change. The workaround is to:
  • Do a fresh installation of VMware BMA 3.1.

  • Export the workflows developed in your current VMware BMA version (VMware BMA 2.0 or 3.0) and import those workflows to VMware BMA 3.1

  • Manually backport any specific configurations done in the previous version to VMware BMA 3.1.
