- It seems code for instanceHA script to run nova_compute was missing in nova-compute-container-puppet.yaml due to which nova-compute were still using old code[1] in file[2] restart the container

~~~
            nova = client.Client(version,
                                 region_name=options["os_region_name"][0],
                                 session=keystone_session, auth=keystone_auth,
                                 http_log_debug=options.has_key("verbose"),
                                 endpoint_type=nova_endpoint_type)

[2] /var/lib/nova/instanceha/check-run-nova-compute

Workaround:-

1) Adding below tasks bind mouting the new "check-run-nova-compute" in /usr/share/openstack-tripleo-heat-templates/deployment/nova/nova-compute-container-puppet.yaml 

~~~
1126                 # This code is partial copy of logic in podman installation
1127                 - name: is Instance HA enabled
1128                   set_fact:
1129                     instance_ha_enabled: {get_param: EnableInstanceHA}
1130                 - name: install Instance HA script that runs nova-compute
1131                   when: instance_ha_enabled|bool
1132                   copy:
1133                     content: {get_file: ../../scripts/check-run-nova-compute}
1134                     dest: /var/lib/nova/instanceha/check-run-nova-compute
1135                     mode: 0755
~~~

2) Update the plan

~~~
openstack overcloud upgrade prepare ...
~~~

3) re-run the nova-hybrid task to boot the container with new check-run-nova-compute

~~~
nohup openstack overcloud upgrade run --stack msufiyan --playbook upgrade_steps_playbook.yaml --tags nova_hybrid_state --limit all --yes &
~~~

Additional Note:-

Updated check-run-nova-compute will have:-

Version-Release number of selected component (if applicable):
OSP16.1 

How reproducible:
Evertime when we perform upgrade framework[3] in instanceHA bases environment.
