vCenter Enhanced-linked mode update order

[_steez]

Hello,

I have a quick question about updating enhanced-linked mode vCenters.

Currently we're running 2 enhanced-linked mode vCenter servers with version 6.7 Update 3b and would like to update to the newest 6.7 Update 3n.

What is the correct order how to update them - one by one or both together?

Thanks

I have applied patches one by one many times without any problem but in case any problem occurs have a valid backup.
