Symptoms

We recently upgraded our development environment from version 4.6.6 to version 4.6.10.

While trying to package an existing solution we are getting the following error against the workflow:
"Error: Item contains errors that will cause deployment failures"
When I expand that error, I am seeing errors like "'WorkflowsLegal Document Request' Process is referencing the 'Missing ID' Unknown that could not be found."

We packaged another solution successfully, but while deploying it to another server that had version 4.6.6 it gave us the error:
"K2 Package and Deployment does not support this version of the package. Update the solution file and redeploy"

Please let us know how we can address this problem.
