The C-spot

If you allready have a CMS installed in your domain you can remove the old CMS by entering the following command in the lync powershell: remove-csconfigurationstore.

This command will actually remove the service control point in Active Directory that points to your Central Management Store.

When you perform Remove-CSconfigurationStoreLocation the reference is deleted from active directory.

To completely remove references to old topology objects, you will also need to remove some additional entries using ADSI Edit.
