RHEL 6 upgrade to RHEL 7 fails
Hi
I am trying to upgrade RHEL 6 server to RHEL 7. I ran preupg tool, fixed all failed items. Although some needs_action remained, but from my point of view these were not critical. After that I ran ~~~redhat-upgrade-tool --network 7.3 --instrepo https://example.com/pub/rhel7/~~~
After reboot system fails to boot with this message:
[!!!!!!] Failed to allocate manager object, freezing!
Do you have any idea what could be the problem here?
Responses
Is there a reason you are performing an in-place upgrade? In-place upgrades across major releases do not preserve all system settings, services or custom configurations.
Red Hat strongly recommends fresh installations when upgrading from one major version to another. Does Red Hat support upgrades between major versions of Red Hat Enterprise Linux?
Red Hat supports RHEL 6 to 7 upgrades only for specific use cases.
Check your RHEL 6 server meets the criteria. What are the supported use cases for upgrading to RHEL 7?
