Not recommended unless really, really necessary and mandated. Unless you are UC certified, especially if you are the end user, do not try "do it yourself", to avoid unpleasant situations.
However, It is explained in the product documentation.

As Paolo stated this is not to be taken lightly. This is one of those situations where you really want someone who's done mixed mode CUCM clusters before; there are a lot of gotchas to this.
With that said the document to start with would be the Cisco Unified Communications Manager Security Guide. It's critical that you understand how things will work in a mixed mode cluster. A few FAQ that arrise when reading that doc:
