What you need to consider when migrating
There are a number of considerations you should be aware of when you're migrating your store to Shopify:
Do you need to update your store links?
Make sure you set up URL redirects for pages on your current store that customers might have bookmarked. This will minimize the risk of losing customers who return to a page and find it unavailable after you've migrated to Shopify.
Do you have protocol-independent URLs associated with your current store?
Make sure that all your store assets (theme files, stylesheets, or images) are always accessible by removing specific protocols such as
https: from their URLs.
