Q:

Can I delete the "default" policy manager zone in CPPM? Will that create any issue?

No, it's not recommended to delete "default" policy manager zone. In CPPM 6.6 a validation is enabled which prevails the user from  deleting the default policy manager zone and  will display the following error.

If the default zone is deleted it will create problem in a cluster setup. Administrator will not be able to add Subscriber to the cluster and it will fail with below errors:

NOTE:  Administrator would need to collect logs from ClearPass [ Policy Manager » Administration » Server Manager » Server Configuration » Collect Logs]. In the logs the above mentioned error can be verified in PolicyManagerLogs\platform-utils\platform.log.*

This happens because, deletion of  default zone will cause the insert operation for new node to fail in the publisher.  

In this scenario if we re-add the default zone and try to bring the cluster setup it should work.
