I have 2 r3.xlarge AWS EC2 instances that are convertible to r4.xlarge. They are both running Exchange 2016 on 2012R2. I have tried two methods so far:

  1. Changed instance type and booted up
  2. Created AMI and Launched a new instance with it

In both cases, the servers became unreachable and passed only 1\2 checks. I've attached the Elastic IP to both with no results.

Am I missing something here? Does something need to happen to these instances specifically because they're running Exchange?

  • what does access/event logs say when retrieved from web console? – Shailesh Sutar Feb 8 '18 at 16:36
  • You mentioned that they are r3.xlarge. Was that before or after? What was the other instance type? – Michael - sqlbot Feb 8 '18 at 23:20
  • I have fixed the instance types. – Nico J Feb 9 '18 at 16:43
  • Shailesh, what logs are you referring to? – Nico J Feb 9 '18 at 16:51

In order to upgrade from r3.xlarge to r4.xlarge, you will have to install the new ENA and PV drivers from Amazon.
