Symptom
You are getting the error Phase Transition from UG2_DEV to RAD not allowed in Project Type ONE_OFF while trying to activate the solution from SDK.
Reproducing the Issue
- Login to SDK.
- Open the solution.
- Navigate to the tab Implementation Manager.
- Click on the Activate icon.
- Error occurs.
Cause
The reason for the error message is that the activate is executed from Implementation Manager, which is not allowed after the solution is upgraded.
Resolution
You should right click on the solution and choose Activate-> All Items, the solution will be activated without any issues.
Note: If the solution is in Deployed status , the solution explorer level activation will be greyed out and the reactivation/ activation from implementation manager is used when there are any new patch solution which is failed or not activated.
In this case solution is already activated, so you do not need to reactivate the solution again from your end.
