When you migrate the Orchestrator database from one instance of Microsoft SQL Server to another and then try to open Orchestrator Designer in Microsoft System Center 2012 Orchestrator or in System Center 2012 R2 Orchestrator, Orchestrator Designer starts to open and then generates a prompt that indicates that the license key has expired. When you enter a valid key and then click OK, the same prompt appears.

For all the details as well as a resolution, please see the following:

KB2920037 – Orchestrator Designer generates a prompt for a license key after you migrate the Orchestrator database (http://support.microsoft.com/kb/2920037)

To resolve this issue, follow these steps:

Stop the Orchestrator Management service.

Open the Orchestrator database on the new instance of SQL Server.

Open a new query, and make sure that the Orchestrator database is selected.

Execute the following two lines on the database, one at a time:

Delete the old key:

[Microsoft.SystemCenter.Orchestrator.Cryptography].[DropOrchestratorKeys]

Create the new key:

[Microsoft.SystemCenter.Orchestrator.Cryptography].[CreateOrchestratorKeys]

Start the Orchestrator Management service.

When you now open Orchestrator Designer, you are again prompted for the key. When you enter the key, the key works as designed.
