Hi
We are performing a SBS2011 > Server 2016 Std migration
Emails have already been migrated a while ago to Office 365. We will never use an on-premise Exchange 20xx.
The migration guide (https://server-essentials.com/support/migrate-sbs-2011-to-windows-server-2016-standard-or-datacenter) asks to install all SP & RU to bring the Exchange server to the latest Service Pack & Update Rollup
Are we required to install all Exchange 2010 latest SP & RU in this case before migrating the other parts of Windows?

No, you don't need to do that but remember that part of the migration is that you uninstall Exchange Server 2010 from the SBS 2011. The guide to uninstall Exchange Server 2010 is written with all service packs and CU's installed. It could be that you run into issues if you do not have the latest installed but it can also work just fine...
