What is the process to downgrade the NMON Performance Monitor for Unix and Linux Systems app from 1.6.13 to 1.6.12?

I just upgraded to 1.6.13. The nmon data for various panels has changed from line to scatter graphs. I'd like to downgrade back to 1.6.12 ( I'll put in another ticket about the scatter graph issue ) Version of the Nmon core application deployed - 1.6.13 Versions of addon packages (TA-nmon and PA-nmon) deployed, if any - None Versions of Splunk in use - 6.3.0 Brief description of your deployment: One server running all services Type of Operating Systems - AIX and Linux Mention any local configuration in use within your deployment - running scp command to gather the nmon files and monitoring the repository directory for new files.
