Easy question looking for easy answer

I am wondering if it is ok to upgrade all of my users mailfiles to the 8.5 template even though some of my users aren’t yet on Notes 8.5?

Will there be any issues with these non-8.5 users?

Thanks

Subject: Yes, supported while upgrading

like calendar federation or right-click menus
