What Adobe software are you using? (It's usually better to post in a software-specific forum than here. A moderator can move your post to the right forum if you say what you're using.)
there is no OOTB option to convert an AEM page to AMP.
You need to follow guideline listed here.
This will be a custom project requirement as per se. One possible way I can suggest, you can configure a live copy and rollout configurations for AMP pages.
Then You can use data attributes in every page to list down the AMP specific properties and use rollout configurations to translate your whole website into AMP project.
If a user request AMP page, you can access the server from amp directory just like we deliver mobile pages for the mobile request.
www.yourproject/amp to display you amp pages.
