Hi @Robert1985Lee ,
1. Run these commands on your vCenter(If PSC is external, run the commands on PSC instead)
/usr/lib/vmidentity/tools/scripts/lstool.py list --url http://localhost:7080/lookupservice/sdk --type com.vmware.vr.vrms
2. This command should only be run if you have deployed vSphere replication 8.1 or later. Earlier versions do not have this service.
/usr/lib/vmidentity/tools/scripts/lstool.py list --url http://localhost:7080/lookupservice/sdk --type vrUi
3. This will list service ID for vSphere replication. Run following command to un-register:
/usr/lib/vmidentity/tools/scripts/lstool.py unregister --url http://localhost:7080/lookupservice/sdk --id 608BF497-A198-40C1-9866-545533A488BE --user 'administrator@vsphere.local' --password 'VMware123!' --no-check-cert
Note: Replace value of ID with service ID captured from step.1 & 2. Update SSO user name and password before executing this command
Hope that helps
