VNA domains not showing at Portal Groups under VNA domain group

Issue/Introduction

We have vnagateway_A, vnagateway_B at different locations.

vnagateway_A migrated as vnagateway_C host following steps mentioned;  https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/virtual-network-assurance/23-3/migrate.html

Now we have  vnagateway_B and vnagateway_C.

There were domains at vnagateway_C, vna swagger UI shows those domains.

However, Portal UI  Groups  those VNA domains from vnagateway_C  are missing. This makes it unable to filter dashboards or view dashboards, and so on. 

Environment

VNA 23.3.13

Cause

When the migration occurred, the DA got an update that caused it to delete its inventory associated with the VNA being migrated.  It then never recreated them because there was a full update that has been processed since due to the fact that we have a piece of code that is causing our processing to be backed up by days/weeks.  

Resolution

Delete the VNA Gateway, and then wait for a period of time for all the updates to be processed
The vna.log file on the DA can help determine when this completes, and then re-create the VNA Gateway.
