The third step in this process is to merge the imported policy with the SCM baseline policy. Keep in mind that some configurations and settings will be lost when you merge an existing GPO with the SCM baseline policy. For example, service-related or ACL configurations may not be preserved when you associate and merge with an SCM baseline policy. If you have these types of configuration in your GPO and want to retain them, you may need to split the GPO and use two separate GPOs. Inside the SCM, the import process is to map these configurations with the SCM library to preserve these settings. If it doesn't match or map, these settings will be dropped from the new baseline policy. For this exercise, my assumption is that you don't have a custom configuration or settings in the imported policy. The following steps can be used to Associate and Merge a GPO-based policy into an SCM-based policy:
