Key quotes
· 4 pulledI'm working on expanding the AI Shipping Labs website and wanted to migrate its current version from static GitHub Pages to AWS.
The migration strategy itself was reasonable, but the problems came from how I executed it.
This way, everything would already be inside AWS, and the final switch would be seamless.
My gradual plan was: Move the current static site from GitHub Pages to AWS S3, Move DNS to AWS so the domain is fully managed there, Deploy the new Django version on a subdomain, When everything works, switch the main domain to Django.
