Symptoms

During performing pre-check for MN migration from RHEL/CENTOS 6 to RHEL/CENTOS 7 (KB 130182 or 130183):

2017-03-29 21:09:10.371 [INFO] Log file has been created: /var/log/pa/rhel7-migration-precheck.log
2017-03-29 21:09:10.674 [ERROR] For some components detected properties with NULL values. Please follow https://kb.odin.com/130540 to resolve an issue.
<...>
2017-03-29 21:09:10.674 [ERROR] Check is failed

Cause

Shortcomings of previous upgrade actions for some components.

Resolution

  1. Please make sure you have actual version of migration scripts (check KB 130182 or 130183)
  2. Launch the tool actions_before_migration_to_rhel7.py from /usr/local/pem/bin/ with the option --action fix_null_properties_values:

    /usr/local/pem/bin/actions_before_migration_to_rhel7.py --action fix_null_properties_values
    

    The result should be:
