Shopify Post-Migration Bug Checklist to Run

Shopify migration bugs usually cluster around inventory policy, currency labels, and shipping setup in the first two weeks. I run the same checklist after every move: inventory behavior first, then price display, then delivery options, then redirects. That order puts shopper trust first and cleanup second.

Migrations move a lot of rows at once, so small data quirks become visible fast. I treat each one as a data issue to correct, not as anyone's fault. The store did its job getting here; my job is to tidy what the move shook loose.

Shopify Migration Bugs: Inventory Policy First

I start with per-variant inventory policy because it decides whether shoppers can buy what they see. Shopify documents the native toggles for tracking quantity and whether to keep selling when inventory runs out, and bulk correction beyond that is custom work. Their inventory tracking Help is the reference I keep open Shopify inventory tracking Help.

On a recent build, hundreds of variants needed the deny behavior corrected in bulk, and we handled it with custom Admin API work rather than clicking through each row. Per-variant inventory policy exists natively; bulk correction was custom Admin API work. That distinction matters in your handover notes so future edits use the right method.

I verify with the exact storefront wording. I open products that should be unavailable and confirm the button state matches the inventory count. I also check the admin label Continue selling when out of stock on a sample of variants to confirm the policy saved. My dry rule here: if I can't explain the setting in one sentence, I re-check it.

Currency Labels That Confuse Shoppers

Next I check currency labels in every market view. After one import, NGN figures were labelled as USD, which looked fine in the sheet and wrong on the page. We treated it as a price and currency data correction, fixed the rows, and re-tested product, cart, and checkout views. Shoppers shouldn't have to guess which money they're seeing.

I test with market switcher views and direct links. I record what each market shows for the same product, and I confirm the cart keeps the same labels through checkout. Where GHS local display depends on processor support, I confirm the fallback wording stays consistent instead of flipping between labels. Shopify's currency customization notes explain the fallback behavior Shopify currency display Help.

If you want the pre-launch side of this story, my Shopify migration checklist that protects SEO covers redirect mapping and domain checks. For price row cleanup at scale, my bulk pricing edits with Python CSVs shows the cleaning order I follow. You can also browse my selected Shopify work for build context.

Shipping Setup Overlaps and Redirect Leftovers

Then I review shipping setup for overlaps. Duplicate delivery zones cause confusion at checkout, so I consolidate into one clear setup per market with general names only. I don't copy error text or private specifics into my notes; I just record what the shopper sees and simplify until the choice is obvious. One clear option beats three similar ones.

I also re-test redirects from my original map. Shopify notes that only broken destinations can be used as redirect sources and that certain prefixes are reserved, so I check misses against those rules in their URL redirect Help. I fix the source row rather than stacking another redirect on top.

I finish with a full shopper walk on mobile. I search, I open a collection, I choose options, I add to cart, I start checkout without paying, and I confirm currency, inventory messages, and delivery choices stay steady. If anything flickers between markets, I note the exact clicks so I can reproduce it. I also open the search results page and two older blog posts, since those templates often link to retired handles that my redirect map missed. I fix each leftover link at its source and re-test the same path the next day.

Takeaway: My Post-Migration Bug Checklist

Run this in order during week one and week two. Note dates and what you changed so you can trace cause and effect.

• Inventory policy: sample variants across collections, confirm tracking and sell-through behavior matches intent.
• Unavailable states: open products with zero on hand and confirm button and messaging match the counts.
• Currency labels: record product, cart, and checkout labels per market for the same items.
• Data correction: fix mislabelled price rows at the source, re-import cleanly, re-test all market views.
• Delivery clarity: look for overlapping zones per market, consolidate to one clear setup, test checkout choices.
• Redirect sweep: test top old URLs, fix source rows, avoid chains, keep history with dates.
• Mobile walk: repeat the full shopper path on a phone and save screenshots with dates.

Why do some fixes revert after a re-import?

Because the source sheet still holds the old values. I fix the source file first, then re-import, then verify on the live page. If you edit only in admin and later reload the same sheet, the old data returns. Source-first saves repeats.

How do I know when I'm done?

When each market shows steady currency labels, unavailable items behave, delivery choices read clearly, and top redirects resolve without chains. I also like a quiet week in Search Console with no new 404 spikes. Done means boring, and boring is good here.
