Uninstall GCRS

When you finish syncing data with Google Calendar Resource Sync (GCRS), you can uninstall the product.

Step 1: Remove the components

1. Open the migration server and locate the program files for GCRS.
2. Select the following components:
   • Administration database
   • Log databases created by the system
3. Right-click and select Delete Database.

   If you have replicas, check the Also delete replicas box.

4. Click OK.
5. Make sure the GCRS template files have also been deleted from the server. If they have not, manually delete them.

Step 2: Remove the service account DLL

If you completed these steps when you uninstalled GWMHN or GCCHN, you don't need to complete them again.

1. Shut down the migration server.
2. On the same server, start a command prompt in elevated mode.

   To do this, point to the command prompt icon in the Windows Start menu, right-click, and select Run as administrator.

3. To locate where the dynamic link library (DLL) is registered, enter the following command:

   reg query HKLM\SOFTWARE\Classes /s /f service_account_com_dll.dll

4. If the DLL is not registered, skip to step 7. Otherwise, move to the folder for your version of Domino:
   • 64-bit version–Go to C:\Windows\System32.
   • 32-bit version–Go to C:\Windows\SysWoW64.
5. To deregister the service account DLL, enter the following command:

   regsvr32.exe -u C:\IBM\Domino\service_account_com_dll.dll

   Replace IBM\Domino with the path to your Domino program folder.

6. Delete the service_account_com_dll.dll files.
7. Restart the migration server.
