Can we run CMS 12 and CMS 13 sites in the same opti graph instance?

Based on the CMS 13 migration docs I would be careful with this setup.
CMS 13 introduces breaking changes in the Graph schema compared to CMS 12 and the documented migration path seems to create a separate CMS 13 project / Graph instance rather than reusing the CMS 12 one

Is that possible? since the schema is so different?
it is two different sites and page types
