I don’t know anything about Azure but the PHP upgrade process is done via the web server and isn’t a part of WordPress itself.
WordPress is written to take advantage or even require a certain version of PHP but that is up to your web host to provide that.
Contact your hosting provider for more help.
Let us know if you need more info or help yet but we are limited in what we can do about this process.
Docs seem to be kind of difficult to get hold of…
JNash is right, this is outside of WordPress, but that having been said, see if this helps:
