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:
- Changed instance type and booted up
- 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?
