Question 1

Will our organic Google search traffic drop after migrating to Shopify Plus?

Accepted Answer

No. When executed with rigorous technical engineering, your organic traffic will not drop. The primary reason migrations fail with amateur agencies is incomplete 301 redirect mapping, changed URL hierarchies without redirects, missing metadata, and lost schema markup. FactoryJet performs a complete pre-migration crawl of your entire domain, programmatically maps every single legacy URL to its exact Shopify destination with 1:1 301 redirects, preserves all title tags, meta descriptions, image alt attributes, and JSON-LD structured data, and monitors Google Search Console indexing in real time during cutover.

Question 2

How do you prevent 404 errors during migration?

Accepted Answer

We generate an exhaustive inventory of every URL indexed in Google, Bing, and historical server log files using automated crawling tools. We construct a 1:1 redirect map where old paths (e.g., /catalog/product/view/id/1234 or /shop/apparel/item.html) point directly to their new canonical Shopify URLs. This redirect map is loaded at the edge (via Cloudflare Workers or Shopify native URL redirects) so crawlers and visitors are instantly forwarded to the correct page without hitting 404 error pages.

Question 3

Can you migrate 100,000+ SKUs with complex product variants and custom attributes?

Accepted Answer

Yes. We regularly migrate high-volume enterprise catalogs with 50,000 to 500,000+ SKUs containing complex product variations, multi-tier pricing, custom engraving text, file uploads, and technical specifications. We design custom ETL scripts that convert legacy relational tables and EAV models into Shopify native product options (up to 2,000 variants per product on modern Shopify) and structured Shopify Metafields for rich technical attributes.

Question 4

What happens to our historical order records and invoices?

Accepted Answer

We migrate complete historical order records, line items, historical customer billing and shipping addresses, tax breakdowns, discount codes, shipping fees, fulfillment tracking numbers, and refund histories into Shopify Plus using Shopify’s Order API. Your customer service team retains full visibility into past customer purchase history directly within the Shopify admin, and past orders synchronize fluidly with your ERP.

Question 5

Can existing customers log into Shopify without resetting their passwords?

Accepted Answer

Yes. On Shopify Plus, we implement Shopify Multipass authentication or custom cryptographic token bridging. This allows existing customers with password hashes (bcrypt, Argon2, SHA-256) to log into the new Shopify store fluidly on their first visit without requiring disruptive mass password-reset email campaigns, preventing customer friction and cart abandonment.

Question 6

What happens to customer loyalty points and store credit during migration?

Accepted Answer

We extract loyalty balances, VIP tier statuses, and store credit ledger records from legacy systems (such as Yotpo Loyalty, Smile.io, MageWorx, or custom database tables) and import them directly into your new loyalty app on Shopify Plus or native Shopify Customer Account metafields, ensuring zero customer balance loss.

Question 7

Will our store experience any downtime during the platform migration?

Accepted Answer

No. Your existing store remains 100% active, fully functional, and capable of taking orders right up until the exact moment of DNS cutover. We perform all development, data imports, design, and integration testing on private staging environments. During the scheduled cutover window (typically during your lowest traffic hour), we run a rapid delta sync of newly placed orders and flip the DNS records at the edge, achieving zero customer-facing downtime.

Question 8

How do you handle orders placed on the old store right before DNS cutover?

Accepted Answer

We utilize an automated Delta Sync protocol. Immediately following DNS switchover, our migration script queries the legacy platform’s database for any orders placed during the final transition window and imports them into Shopify Plus while simultaneously forwarding them to your warehouse or ERP, guaranteeing zero lost orders or double-fulfillments.

Question 9

How does Shopify Plus connect to our ERP system (NetSuite, SAP, Microsoft Dynamics)?

Accepted Answer

We build enterprise event-driven integration pipelines between Shopify Plus and your ERP using modern webhooks, Amazon EventBridge, Celigo, Boomi, or custom middleware microservices. The integration manages real-time bidirectional syncing of inventory counts across multiple warehouse locations, automated order ingestion, shipment tracking updates, and financial reconciliation.

Question 10

What happens to our custom third-party integrations and shipping carriers?

Accepted Answer

During Phase 1 discovery, we audit all third-party systems, including 3PL warehouses, shipping rate calculators (FedEx, UPS, DHL, Freight), custom tax calculation engines (Avalara AvaTax), and marketing platforms (Klaviyo, Gorgias, Attentive). We reconnect these platforms to Shopify Plus using official enterprise connectors or custom private apps built on Shopify Functions.

Question 11

Can you migrate our complex B2B wholesale pricing tiers and company accounts?

Accepted Answer

Yes. Shopify Plus includes native B2B wholesale functionality. We migrate company profiles, location-specific price lists, quantity price breaks, Net payment terms (Net 15/30/60), and custom product catalogs directly into Shopify native B2B, eliminating the need for expensive third-party wholesale apps or duplicate clone stores.

Question 12

How long does an enterprise Shopify migration take?

Accepted Answer

A standard enterprise Shopify Plus migration takes between 6 and 12 weeks depending on catalog complexity, custom design requirements, and ERP integration depth. FactoryJet provides clear milestone schedules with dedicated weekly sprint reviews so your team always knows exact progress.

Question 13

What is the pricing model for a Shopify Plus migration?

Accepted Answer

FactoryJet operates on transparent, fixed-price sprint pricing based on the scope of your migration (catalog size, design complexity, ERP integrations, and custom apps). There are zero hidden fees, hourly overage surprises, or perpetual agency licensing costs. You receive a guaranteed fixed scope and delivery timeline.

Question 14

Who owns the code and intellectual property after migration?

Accepted Answer

You do. 100%. All custom theme code, headless Next.js repositories, migration ETL scripts, middleware pipelines, and configuration documentation are committed directly to your private GitHub or GitLab repository with full intellectual property ownership transferred to your company upon launch.

Question 15

How do you handle delta order synchronization during the DNS propagation window?

Accepted Answer

DNS propagation can take anywhere from a few minutes to several hours across global ISPs. During this window, some shoppers may still hit the old server while others hit Shopify Plus. Our automated delta sync worker monitors the legacy database continuously, capturing any orders placed on the old platform and streaming them into Shopify Plus via the Orders API in near real-time, preventing fulfillment discrepancies.

Question 16

How are custom product bundles, tiered quantity discounts, and custom pricing migrated?

Accepted Answer

We utilize Shopify Functions, Shopify’s high-performance server-side WebAssembly logic engine. Instead of relying on slow client-side JavaScript apps, we engineer custom discount and cart validation rules that execute natively within Shopify’s checkout backend, ensuring sub-50ms execution speed and frictionless mobile conversion.

Question 17

What happens to customer subscription tokens and recurring billing contracts?

Accepted Answer

We perform secure payment token migrations across payment gateways (e.g. Authorize.net to Shopify Payments / Stripe) using PCI-compliant token exchange protocols. We import active subscription contracts into platforms like Recharge, Skio, or native Shopify Subscriptions without requiring subscribers to re-enter their credit card numbers.

Question 18

How do you migrate custom gift cards, store credit, and loyalty points?

Accepted Answer

Unused gift card balances and store credit ledgers are exported from your legacy database and created via Shopify Plus Gift Card APIs as active customer credits. We verify total outstanding liability before and after migration to ensure 100% financial ledger reconciliation with your accounting department.

Question 19

What is the difference between a direct API ETL migration and an app-based migration tool like Cart2Cart?

Accepted Answer

Automated SaaS tools like Cart2Cart use generic cookie-cutter field mappings that frequently truncate custom metafields, corrupt variant hierarchies, fail to map complex 301 redirects, and cannot handle enterprise ERP synchronization. FactoryJet writes custom, auditable ETL scripts tailored specifically to your relational database schema, providing line-by-line verification, data sanitization, and rollback safety.

Question 20

How do you audit and verify that 100% of URLs are correctly 301 redirected?

Accepted Answer

We execute automated end-to-end crawl testing using automated headless browser scripts. Our testing engine sends HTTP GET requests to every single legacy URL in your historical sitemap, checking that the HTTP status code is exactly 301 (Permanent Redirect) and that the destination URL matches the canonical Shopify target without redirect chains or intermediate 404 errors.
