How should I setup a clustre with a combination of Multi-Rail enabled nodes and non-Multi-Rail enabled nodes? (#TODO)

What should I do if I upgrade from a non-Multi-Rail Lustre version (<=2.10 ) to a Multi-Rail Lustre version (> 2.10) with regards to Multi-Rail?

Are there any specific consideration when configuring linux routing for LNet Multi-Rail node?
