What happens to my existing apps post VPP using Configurator

Hi there,

I work for a library and we have invested a fair amount on the apps for two of our ipads. I've just heard of Configurator and would love to get all 8 of our ipads setup with it but I'm worried that the existing apps (on a private account) will be gone. Has anyone had experience with this or know if it's possible to preserve the existing apps.

Thanks,

Kevin
