There are a few things you need to do before moving your website to Shopify. You will need to export your products, customers, and orders from your current platform to Shopify. You can use a CSV file to do this.
Once you have exported your data, you will need to import it into Shopify. You can do this by going to the Shopify admin and going to Products > Import.
Next, you will need to choose a theme for your Shopify store. You can do this by going to Themes > Add New Theme.
Finally, you will need to add your domain name to your Shopify store. You can do this by going to Settings > Domains.
Now that you have everything set up, you are ready to move your website to Shopify!
