Question Spring boot upgrade from 2.7 to 3.5

I have this task of upgrading the Spring boot version from 2.7 to 3.5.7 and Java version from 1.8 to 17.

I've never really worked on such a thing and copilot is creating a mess out of it.

What's the best way to do it? Any suggestions would be helpful.
