reasons not too sure a staged migration on exchange 2010 if it works?

[Deleted]

Hello, 

What is the exact reason not to do a Staged Migration from 2010 to office 365 if this works? what issues does this cause? 

Also, why would Microsoft just not prevent a Staged Migration to run, if this is not supported?

It's not really the reason NOT to run a staged migration, just that a cutover migration is a bit  more seamless process for end users under a certain amount (MS recommend...), and seems to be the most commonly preferred choice.
