[Red Hat Insights can be used only to run the pre-conversion analysis on CentOS Linux 7 systems.]{{admonition note}}
In this quick start, you will connect and run a pre-conversion analysis on CentOS Linux machines on the Red Hat Hybrid Cloud Console. The task generates a report that summarizes potential problems and suggests recommended solutions to help you convert to RHEL.

To assess whether your CentOS Linux systems can be converted to RHEL, run the Pre-conversion analysis for converting to RHEL task. The pre-conversion analysis generates a report summarizing potential problems and recommending solutions. The report also helps you decide whether it is possible or advisable to convert to RHEL.<br>

Each issue is assigned a severity level:
- **Inhibitor:** This would cause the conversion to fail because it will likely result in a deteriorated system state. This issue must be resolved before converting.
- **Overridable inhibitor**: This would cause the conversion to fail because it will likely result in a deteriorated system state. This issue must be resolved or manually overridden before converting.
Skipped: The test could not run because of a prerequisite test failing. This issue could cause the conversion to fail.
- **Warning:** This would not cause the conversion to fail. System and application issues might occur after the conversion.
- **Inhibitor:** Would cause the conversion to fail because it is very likely to result in a deteriorated system state. This issue must be resolved before converting.
