CPM Server may fail to finish configuration when upgrading from v2.1.3 to v2.1.3a using AMI

CPM Server may fail to finish configuration when upgrading from v2.1.3 to v2.1.3a using AMI

At the end of configuration, when clicking at the "Click here to start CPM" link, CPM may go back to a page asking to enter instance id. Rebooting the instance and going directly to the /console URL doesn't help.

The following error can be found in config_shell_commands.log:
perform_shell_commands(:298)  Unknown CPM version - 2.1.3
This issue is limited to v2.1.3a AMI.

If you have found this error in the logs, please upgrade to the latest 2.1.X version.
Reference defect number - 4836f91619, fixed in v2.1.3b
