GRIDNET Core 1.2 - The Monumental Release is Now Available

Hi all ,very happy that the update has arrived ,well done!

I have a query/question given that I have the previous version already installed which knows my current address id, am I required to uninstall the previous version and do a clean install of core 1.2, if so will that effect the id relationship with core and phone app address key ,id etc. What I mean is would I lose my current id which would be replaced by a newly generated address private key etc on the mobile app.
