Any general advice for updating older versions of WordPress?

Hey all, I’m planning on helping a client update their older version of WordPress and I want to learn what would be the best way to go about this!

Is there a certain best order in updating things such as: PHP, WordPress Core, Plugins, Theme?

When finally publishing the updates, do you upload a backup of your local changes to the site or do you follow the steps you did locally to update?

If the theme is old or deprecated (in my case [iFeature Pro 5](, would you recommend to migrate to a different theme?

What would be the best way to recreate the client’s WordPress setup locally (LocalWP, Docker)?

Any general advice is also appreciated, thanks!
