The Billing Online Store node is being migrated to RHEL7 per the following instruction:
#130128 Migration of Odin Automation 7.0 Billing Online Store server from RHEL 6 to 7
Step 6.4 from the instruction cannot be completed. When pressing Reregister button the following error appears:
The Online Store node migration is being performed prior to the OA Management Node migration.
Due to this fact, pre-migration action, which fixes incorrect package properties, was not completed.
Incorrect properties values do not allow node re-registration.
Fix incorrect values using the following script from the migration tool:
# /usr/local/pem/bin/actions_before_migration_to_rhel7.py --action fix_null_properties_values
