How to move domain without losing SEO or subscription payments

I recently rebranded this website, moving from one domain to a new domain. In doing so, I had three major concerns: I’d lose all the SEO value I’d built up over the years for the previous domain – and therefore all the traffic I get from search
I’d no longer be able to collect recurring payments for plugins purchased from the site on the old domain
Users would not be able to get automatic updates for new versions of products
This is a step-by-step account of everything I did to ensure that my worst fears weren’t realised.
