ArcMC framework upgrade stuck at Change to upgrade-to version
I am trying install new connector framework from version 126.96.36.19922.0 to 188.8.131.5287.0 from ArcMC (v2.9.5). I have uploaded AUP file to the repository, then in Node management I have chose container and proceeded framework upgrade. Upgrade itself stucked at Change to upgrade-to version (screen). Connector is down, when I manually started it, upgrade process fails at "Starting Connector" and version remain old.
Thanks for your answers
