Hi,
Thank you both of you for your kind suggestions.
We are using leap-upgrade tool to upgrade. In upgrade there is no issue. We have a health checkup also post upgrade.
The issue is in VMware but not sure when creating manually the “Snapshot the virtual machine memory” is set to Yes but when I am creating the snapshot through ansible automatically it is setting as No. This is something with VMware maybe..
- Name: Create VM snapshot
Uri:
User: “ {{ snapshot_user }}”
Password: “{{ snapshot_Password }}“
force_basic_auth: true
Method: post
Body_format: json
Body: |-
{
“Hostname”: “{{ vm_hostname }}”,
“Task”: “ create”,
“Snapshot_name”: “upgrade-{{vm_hostname}} “
}
Status code: 202
Register: snapshot_result
Regards
PD

That's a RHEL problem. It's not an operation supported by RHEL.
Updating the critical system libraries, such as glibc and the python
on which RPM is based, and RPM itself, is likely to trip over a *lot*
of problems without quite a lot of research and debugging. From
decades of experience with Red Hat based operating systems, I
recommend very strongly against this approach.
If I may suggest, take a disk image of the old system and build a new
system, with content copied as needed to configure the new system.
