Uninstall GCCHN

When you finish migrating data with Google Calendar Connector for HCL Notes (GCCHN), you can uninstall the product.

Step 1: Remove the components

Open the migration server and locate the program files for GCCHN.
Select the following components:
- Administration database
- Log databases created by the system
Right-click and select Delete Database.
If you have replicas, check the Also delete replicas box.
Click OK.
Make sure the GCCHN template files have also been deleted from the server. If they have not, manually delete them.
(Optional) Go to your directory serverInternet protocolsDomino Web Engine and set Run web Agents and web services concurrently to Disabled.

Step 2: (Optional) Remove service in the Admin console

You must be signed in as a super administrator for this task.

Sign in with a super administrator account to the Google Admin console.
If you aren’t using a super administrator account, you can’t complete these steps.
Go to Menu Apps > Google Workspace > Calendar.
Requires having the Calendar > Settings administrator privilege.
Click Calendar Interop management, and uncheck the Enable Interoperability for Calendar box.
Click Save.

Step 3: Remove the service account DLL

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

Shut down the migration server.
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.
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
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.
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.
Delete the service_account_com_dll.dll files.
Restart the migration server.

Step 4: Change the calendar value of each user

In the Domino directory, check the Calendar value for each user. If the value is set to Google, change it to Notes.
