Thanks Kumaran for active participation.
1. We have a cluster with 8 hosts and added that cluster to VRA.
2. Now because of demand - I have moved 2 Hosts to another vCenter - not managed by VRA
3. Still endpoint is showing these Two ESXi as two different entities
4. So I need to do a cleanup such that those wont showup
Yes you can remove the inactive hosts as mentioned in the below post. Make sure you choose the correct version of the script and Backup the DB. And better to get vmware support prior if required.
