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.
VNA 23.3.13
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.
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.
