Question What is the best practice for cloning a Plesk instance on AWS ec2

[peteeeeeee]

My site is hosted in AWS ec2, after a certain amount of time, the site traffic growing up, so I decided to add one more ec2 and site behind a load-balancer to distribute network or application traffic.
I create an image from the original ec2 and create the second ec2 instance, it is working fine.

Just wonder any best practices for this cloning action.

1. How can I generate a new domain for the second instance
   I was able to access the Plesk admin panel via Plesk generated domain with https(https://xxx-xxx.1-2-3-4.plesk.page:8443/), but the cloned instance, I can only access it via IP address(5.6.7.8:8443)
2. I found Plesk license keys are the same between two instances, any way I can update it, or should I update it? (not a crucial issue though)
3. Any action I should take after cloning the image with Plesk?
