Chapter 5. Reviewing the pre-conversion analysis report using Lightspeed

Procedure

1. Log in to the Red Hat Hybrid Cloud Console and go to Red Hat Enterprise Linux > Lightspeed for RHEL > Automation toolkit > Tasks.
2. Locate the Pre-conversion analysis for converting to RHEL task and click Select systems.
3. Alternatively, log in to the Red Hat Hybrid Cloud Console, go to Red Hat Enterprise Linux > Lightspeed for RHEL > Inventory > Systems, choose a system you want to convert and click Convert system to RHEL label.
4. In the Task name field type the name of the task and select the CentOS Linux 7 systems that you want to analyze for conversion. Click Next.

5. Configure the pre-conversion analysis task with the following settings:

   Do not use the ELS subscription

   Choose this option if you plan to upgrade your RHEL system to version 8 or higher.

   Allow kernel modules outside of RHEL repositories on the system

   Choose this option to allow the pre-conversion analysis to ignore kernel modules that are not part of RHEL repositories.

   Allow outdated kernel on the system

   Choose this option to allow the pre-conversion analysis to ignore when your system is booted from an outdated kernel.

   Allow outdated packages on the system

   Choose this option to allow the pre-conversion analysis to ignore all outdated packages on the system.

6. Click Run task. The pre-conversion analysis can take up to an hour to complete.

   The pre-conversion analysis utility generates a new report in the Activity tab. Select the report to view a summary of issues found in each system. You can also review further by selecting a system to view each issue and, when applicable, a potential remediation in detail.

   Each issue is assigned a severity level:

   Inhibitor

   Would cause the conversion to fail because it is very likely to result in a deteriorated system state. You must resolve this issue before converting.

   Overridable inhibitor

   Would cause the conversion to fail because it is very likely to result in a deteriorated system state. You must resolve or manually override this issue before converting. For more details about which inhibitors you can override, see the step about configuring the settings of the pre-conversion analysis in this procedure.

   Skipped

   Could not run this test because of a prerequisite test failing. Could cause the conversion to fail.

   Warning

   Would not cause the conversion to fail. System and application issues might occur after the conversion.

   Info

   Informational with no expected impact to the system or applications.

7. After reviewing the report and resolving all reported issues, click Run task again to rerun the analysis and confirm that there are no issues outstanding.
