Environment

VMware NSX-T Data Center 3.x
VMware NSX-T Data Center
VMware NSX-T

Cause

There is no ICMP-ALL "default" service on NSX-V.  User defined service.  However, NSXT already has it as a default service.  The service 'ICMP-ALL' on NSX-T is actually a service group containing 2 entries.  Because of this, the plugin considers this NSX-T service as a group and hence it does not process it for duplicate names in this case.
So, we create the API but however the creation of this service fails as per this update, which says that we cannot modify default service on NSX-T.  The migration for this rule fails

Scenario is : if a user defined service on NSX-V exists as a default service on NSX-T with at least 2 service entries, then ns_service plugin does not update the name of this service. hence the API gets created with same service name. This service migration will fail as we cannot update the default service on NSX-T.

Resolution

This will be fixed in a later release of NSX-T.

Workaround:
1.On NSX-v side update the name of service ICMP-ALL to “ICMP-ALL-1”
2. NSXT – Rollback migration using API or UI
3. Start Migration again
