Changing vROPs licensed editions?

I am running an instance of vROPsStandard(as part of VSOM).   I would like to changethe licenseto an Advancedtrial  to demonstrate the dashboard functionality in the Advancededition.   Is this possible without losing data?

If so, can I switch back to theStandardlicenseafter the theAdvancedtrial expires (without losing any data,  I understand I would lose anyAdvancedcreated items)?

Thanks,
