Recreating new webpages

Hi everyone,


Have a website that was mainly coded with some pages built on Elementor. If we are looking to switch these Elementor pages to coding it in, what is the best way to go about it to ensure that SEO does not take a hit?

Is it just a matter of:

1) Creating a new custom URL
2) Recoding the design of the new custom URL
3) 301 redirects from old URL to new URL

Is that pretty much it?

Many thanks

tons of css in wp-editor I guess
