FAQ
Can you migrate all my Shopify Scripts?
Each Script must be assessed individually. Some functionality has a suitable replacement, while other use cases require a different approach or may not be directly supported.
Can you migrate custom discount rules?
Yes, I can assess and implement supported discount logic using Shopify Functions, subject to the applicable API capabilities and your requirements.
Can you migrate shipping and payment rules?
I can review these use cases and implement supported shipping or payment customizations where the appropriate Shopify functionality and merchant eligibility are available.
Will my existing functionality work exactly as before?
The objective is to preserve the intended business behavior wherever possible. However, some legacy features may behave differently or require an alternative implementation. I'll explain any known differences before proceeding.
Can you audit my Scripts before migration?
Yes. You can start with the audit package to identify replacement options, potential limitations, and a suitable migration plan.
