Domain mapping & SSL

Hey guys I need an expert opinion from you. I'm about to switch everything over to https, but I unfortunately had setup all my mapped domains with the Wordpress MU plugin, of which there are 100's. So instead of migrating everything over to your domain mapping plugin, I was hoping you'd have some insights into how I can successfully move over to https:// using a plugin, code (not ideal), etc. I know this is a bit off topic but I'm not sure where else to turn. Thanks for your help!
