Hi all, I am going to do in place upgrade from SCOM 2012 R2 to SCOM 2016 , i will follow the guide from Microsoft, but I have a question due to the high number of gateways in our environment  I might need to do the in phases , so is it ok that a gateway 2012 r2 report to SCOM 2016 Management Server, same as for the agents ?

Thanks in advance.
