Default Dirty flash okay when switching to unified builds

So I have been dirty flashing the nightlies and have had no problems at all.

Now that CM had gone with the unified build I Sam wondering if dirty flashing is okay when going to the unified build for the first time.

I know the whole nandroid backup routine just wanted to see of anyone had done this...

Sorry to post here as a new user I am locked out of the Dev thread.

Thanks
