However, you will need to build your new website. I understand that you don't want to disturb the current theme layout, but as Shopify is a different platform to WordPress some disruption is inevitable because it's not possible to transfer the whole WordPress theme to your Shopify store. .
Not to worry though! You can add a free theme quickly and start editing it to make it look just like your old store, or you could take this opportunity to reassess your UX design and look for areas where you can improve.
I hope this helps! Let me know if you have any other questions.
All the best, Hyde.
