How to update cordova plugins

Hi guys, a general cordova question here where I can’t find a decent answer to.

I have an app with several plugins and I want to update them to the latest versions because some things aren’t working as they should anymore after updating cordova ios to 3.7.0. These are my plugins:

com.phonegap.plugins.barcodescanner 1.0.1 "BarcodeScanner"
org.apache.cordova.device 0.2.9 "Device"
org.apache.cordova.statusbar 0.1.3 “StatusBar”

Can I update them or do I need to remove and re-add plugins in order to update my app with latest plugin versions.

Thanks for helping out!
