I have a MO8 and I am thinking about upgrading to the Montage 8. I have a couple questions:
I have voice libraries that I purchased for the MO. Can I move those over to the Montage?
Along those same lines, I have Songs that I have created on the MO. Can those be moved over to the Montage.
Lastly, are these voice libraries compatible with the Montage?

There is no automatic conversion for MO6/8 to Montage format. I moved from a MO6 to Montage and was able to migrate the content I wanted to keep over manually. Most of the underlying waveforms are fairly easy to find. The parameters all map over too. It's a manual process.
Some libraries will be compatible and some will not be. There is not a comprehensive list. There was a thread here where a user had fed back at least one library that did not seem compatible. Daniel reports some findings here: https://www.yamahasynth.com/ask-a-question/vintage-keys-sound-library-compatibility
