Package ID does not match App ID - Upgrade version 3.0.3 to 3.1

Hello,

I created a workflow in v3.0.3, updated my version to 3.1 and tried to deploy the process in the new software.

I used Workflow Designer 3.1 to open the xpdl file, and tried to deploy, but it did not deploy successfully. I kept getting error: Package ID does not match app ?ID.

I would like to know if there is there something I can do to deploy the process, or do I have to create it all over again?

Thanks for your response.
