Changing platform

I’m currently paying a monthly fee for home automation with a Viewbiquity reseller. It’s been flakey to say the least and a friend of mine mentioned he’d had a lot of good luck with Vera. I’ve only got a scant handful of devices currently - they are all Z-Wave and configured to talk to the Viewbiquity server. Would it be terribly complicated to reprogram those devices to work with VeraLite?

Thanks much!
