I am sure you have enjoyed our Exchange 2013 Coexistence Guide here which was one long blog.
For Exchange 2016 I have decided to divide it into multiple blogs to allow you to complete one component at a time.
Prior to moving to the migration, you need to design your exchange resource requirement and run the Jetstress on the storage. So have a look at this blog of mine to design your exchange.
Here are the migration steps:
Step 1. Install Exchange 2010 SP3 RU11. Check the blog here.
Step 2. Preparing Active Directory for Exchange 2016. Check the blog here.
Step 3. Install Exchange 2016 prerequisites. Check the Blog here.
Step 4. Install Exchange 2016 Server. Check this Blog for unattended installation here.
Step 5. Exchange 2016 CAS configuration:
There are 2 parts of the CAS configuration URLs and Authentications. Multiple active sites add more complexity.

Multiple Active and Active/passive CAS URLs are explained here.
