i have installed Action plan unmanaged EE,UE and DE  2 weeks before in production.It was working fine. last week i tried to deploy some classes and pages into production using changesets. The deployment validation failed as most of the Action Plan classes were below 75%code coverage .I tried deploying using Eclipse IDE .The deployment failed giving list of Action Plan Classes.I am unable to deploy anything in production except to make changes manually.

Do anyone know if there is issue with this app.

We have another Action Plan V2 Managed .We are planning to uninstall Action Plan V3 unmanaged and install this one in production. is it a good idea or Action Plan V2 managed is also having classes with 75% less code coverage.
