I'm a total newbie so any kinda help is highly appreciated.
I used to have an EC2 server in my old AWS account running CentOS 7 (64bit) and a typical LAMP stack with Webmin/Virtualmin and Elastic IP address A. It is hosting 3 websites/virtual hosts.
I did an AMI image over it and redeploy the AMI to a new AWS account using a different Elastic IP B.
After redeploying, some settings are still using the old IP address A. Thus, is there any way to check the entire system to ensure that now the new server and the websites are using the new Elastic IP B or new server? What are the modules should I check? Any online reference available (cos I can't seem to Google any perhaps I'm using wrong keywords)?
P/S: I only know how to use Webmin/Virtualmin.
