Hey everyone! I'm currently working with an Amazon Linux 2 EC2 instance that's reaching its end of life in June. I need to either upgrade or move to a newer instance, but I'd really like to do this without the hassle of manually setting up everything again. We're running PHP along with some extensions and libraries, like ImageMagick, so I want to ensure I can copy those settings over to the new instance seamlessly. Any advice on the best way to accomplish this while keeping our production environment intact? Just to clarify, we're not using Docker for this setup.

One straightforward approach is to take a snapshot of your current instance and then create a new instance from that snapshot. This way, you'll have everything as it is without any manual setup. Just remember to check the instance generation you're transitioning from and to, as there could be minor differences to address across generations!
If your data is stored on a different EBS volume, you can unmount it from the old instance, then create a snapshot, and after that, you can rebuild and remount it onto your new instance. Just ensure everything's backed up properly before you start!
Thanks for the tip! I think the EBS volume is separate, so I’ll definitely look into that.

Yeah, that’s a solid method! Just be mindful of any specific configurations you might still need to tweak.
