When I upgrade a Container subscription to another hosting plan the upgrade Order fails with the following error in log:
Application template [template name] is not synchronized with hardware node [hardware node name] and cannot be installed there automatically.
The new plan includes Application Templates that are not synchronized with the node the Container in question is on.
Please synchronize the templates as it is described in Parallels Business Automation Standard Provider's Guide
NOTE: In case the templates are in the "Registered" status on the Management node it will require to install them on the Management node first.
