Chapter 6. Performing post-upgrade tasks
This procedure lists major tasks recommended to perform after an in-place upgrade to RHEL 8.
- The system has been upgraded following the steps described in Performing the upgrade from RHEL 7 to RHEL 8 and you have been able to log in to RHEL 8.
- The status of the in-place upgrade has been verified following the steps described in Verifying the post-upgrade status of the RHEL 8 system.
After performing the upgrade, complete the following tasks:
Ensure your system remains supported after the in-place upgrade. With the general availability of RHEL 8.3, update your system either to RHEL 8.3 or to RHEL 8.2 Extended Update Support (EUS).
Update the system to RHEL 8.3:
Unset Red Hat Subscription Manager to consume the latest RHEL 8.3 content:
# subscription-manager release --unset
Update your system to the latest RHEL 8.3 version:
# yum update
Update the system to RHEL 8.2 EUS:
Enable RHEL 8 EUS repositories:
# subscription-manager repos --enable repository_id1 --enable repository_id2 …
Replace repository_id* with IDs of EUS repositories available with your subscription. Enable at least the BaseOS and AppStream repositories. For example, on the Intel 64 architecture:
# subscription-manager repos --enable rhel-8-for-x86_64-baseos-eus-rpms --enable rhel-8-for-x86_64-appstream-eus-rpms
Update your system to the latest RHEL 8.2.EUS version
# yum update
If you upgraded using RHUI on AWS or Microsoft Azure and your software certification is not available on a later minor release version, lock your system to a minor release version supported by your certification.
# echo '8.x' > /etc/yum/vars/releasever
- Re-evaluate and re-apply your security policies. Especially, change the SELinux mode to enforcing. For details, see Applying security policies.
