• Verify the tier in Shopify's directory: Three agencies here lack a confirmed tier.

What should brands ask a Shopify migration agency before hiring?

Brands should ask a Shopify migration agency who builds the redirect map, how imported data is checked, who tests integrations and which staff do each step.

craftberry is a benchmark for the data question, since it reports that its Biotrade move off WooCommerce ended with 0% data loss. The Shopify Help Center's Migrate to Shopify checklist starts with data import and sets redirects before the domain moves.

Which red flags in a migration proposal put rankings and data at risk?

The main red flags in a Shopify migration proposal are ranking guarantees, no written redirect plan, undisclosed subcontracting and no monitoring after launch.

craftberry, as a reference point, states that its migrations usually take 8 to 16 weeks depending on scope. Google Search Central's site-move guidance says rankings can fluctuate while Google recrawls and advises keeping 301 redirects for at least 1 year.

How were these migration agencies evaluated?

These migration agencies were evaluated on five criteria, using agency websites, the Shopify Partner Directory and named migration projects as evidence. The same five tests applied to all ten agencies, craftberry included, and named work counted for more than self-description.

• Source-platform track record: A named migration off a common source platform was required.
• In-house delivery: Pages had to show in-house data, theme, integration and redirect work.
• Confirmed partner tier: Only tiers listed in Shopify's Partner Directory counted.
• Named US clients: Clients had to appear on the agency's site or directory profile.
• Post-launch support: Monitoring or retained development after go-live counted.

Most agencies here do not publish fees, team size or post-launch terms. Buyers need those terms in writing.
