Reposting here after suggestion on Stackoverlfow.com that this would be a more appropriate user community.
I have a complex wordpress multisite that is difficult to migrate to another server. I need to upgrade the underlying OS from AWS Linux to AWS Linux 2 for security reasons. Since upgrading the OS on the EC2 instance is not an option, is it possible to create a new AWS EC2 instance running AWS Linux 2 and attach a copy of the existing WordPress volume to the new AWS Linux 2 instance and run WordPress from the new instance . , This would allow me to update SSL/TLS/PHP to more secure versions without having to recreate complex configuration of an existing site on another machine.
