Need help on Silent install to Update existing datecode or New install using same XML files.

[Devidas]

We have some users already using Creo 3 M040-M090 Datecodes and now planning to update to Creo 3 M130. Also few new users which need to install Creo 3 M130. 

We have single image in software store configured for silent Creo install, which makes new install of Creo 3 M130 and not updating the current one on users system. 

My Question is how to configure silent install process to detect existing install datecode and depnding on availibilty status decide for new install or update existing install of Creo datecode?

Any help will be much appreciated.
