I've been using the Bitnami images on AWS Lightsail for a couple of years. Every once in awhile, I'll take the time to create a new instance when there is a new one available from Lightsail and use All-in-One Migration to migrate the old site to the new site.
This is very time consuming and occasionally results in funny things with the migration.
I keep an eye on the changelog at https://bitnami.com/stack/wordpress/changelog.txt
I know using the Bitnami Launchpad, I could grab the latest version.
However, my question is, is there any service out there that essentially manages this process to keep on the latest AWS Bitnami release? Like everytime Bitnami releases a new AWS image, this service would take care of automigrating your website to the latest image?
