The wiki page https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide has a link to my blog:
Alternatively, this blog post by @wimdeblauwe provides a different approach that saves the two step upgrade.
The link should be updated to:
https://www.wimdeblauwe.com/blog/2018/2018-08-30-tip-on-migration-to-spring-boot-2-when-using-flyway/
There is currently a redirect in place, but that redirect will go away in a few weeks and the link would be broken.
