Cause

The access host information is not updated in bp.conf file or registries of the target primary server after the migration.

Solution

Based on the workload, set the following values on the target primary server after the migration is completed using bpsetconfig command.

NUTANIX_PROXY_SERVER = <Target primary Server Name>

RHV_PROXY_SERVER = <Target primary Server Name>

VM_PROXY_SERVER = <Target primary Server Name>
