How to Choose a Shopify Migration Agency

What actually separates a good Shopify migration agency from a risky one — the questions to ask, the red flags to watch for, and why a vague quote usually means a vague plan.

By UVT Team

Choosing a Shopify migration agency comes down to three things: can they show you a specific, itemized plan for your actual catalogue and integrations rather than a generic process deck, do they treat SEO redirect mapping as a core deliverable rather than an afterthought, and will they still be answerable to you after launch, not just before it. Most migration problems trace back to one of these three being skipped, not to a lack of technical skill.

Key takeaways

An agency that can't give you an itemized quote — broken down by data migration, development, integrations and QA — likely hasn't actually scoped your catalogue yet.
SEO redirect mapping should be a named deliverable in the plan, not an assumption that "SEO is included." Ask specifically how they're handling it.
Case studies you can't verify (anonymised ones included) are normal in this industry — most agencies work under NDA. What matters is whether they can speak specifically about your platform and scale, not whether they can show you logos.
Ask what happens after launch. A migration isn't finished at go-live; the first few weeks of monitoring and fixing matter as much as the build.
A Shopify Partner badge (Select, Plus, Premier) tells you Shopify has verified the agency's track record. It doesn't tell you whether they're the right fit for your specific project — ask the fit questions anyway.

Why the wrong agency choice is expensive to undo

A migration touches your data, your SEO and your revenue at the same time. A mediocre website redesign is annoying to live with; a mediocre migration can mean lost organic traffic that takes months to recover, broken integrations that disrupt fulfilment, or a checkout that converts worse than what you had before. The cost of choosing poorly isn't just the money spent — it's the months of recovery afterward, which is why the selection process is worth real scrutiny before you sign anything.

The questions that actually separate agencies

Ask these in the first real conversation, not after you've already committed:

"Can you walk me through how you'd handle our redirect mapping, specifically?" A real answer names tools (Search Console export, a mapping spreadsheet or tool, a QA step before launch). A vague answer ("we handle SEO") is a signal they haven't done this carefully before.
"What's your process for auditing what custom functionality we actually need to rebuild?" Good agencies have a real triage process: native to Shopify, available via an app, or genuinely custom. If the answer is "we'll figure it out as we go," that's where budgets run over.
"What does the first two weeks after launch look like?" A migration that ends at go-live, with no plan for monitoring Search Console, checkout completion and support tickets, is leaving the riskiest part of the project unmanaged.
"Can you give me an itemized quote, not a single number?" Data migration, development, integrations and QA, broken out separately. If they can't break it down, they likely haven't scoped it specifically.
"What happens if something's wrong after launch — is that included, or a new project?" Get this in writing before you sign, not as a conversation after something breaks.

Red flags worth taking seriously

A single lump-sum quote with no breakdown, offered before any real discovery call about your catalogue, integrations or customizations.
Vagueness about SEO redirects specifically. This is the single most common way migrations lose organic traffic, and a good agency should be able to describe their process in detail, unprompted.
No clear post-launch plan. If "launch" is where the relationship ends, you're on your own for exactly the period when issues are most likely to surface.
Pressure to decide quickly, especially paired with a vague scope. A real migration plan takes real discovery time to produce.
Case studies that feel too polished to be true, or refuse to discuss the kind of technical problem specific to your platform at all. Confidentiality around client names is normal; vague evasiveness about actual technical approach is not.

What a Shopify Partner badge does and doesn't tell you

Shopify's partner tiers (Registered, Select, Plus, Premier, Platinum) are earned through demonstrated commercial impact — revenue, new merchants onboarded — not by self-nomination. A higher tier is a real signal that an agency has delivered consistent results at scale. What it doesn't tell you is whether that agency is the right fit for your specific migration: your platform, your catalogue size, your integrations, and how your team prefers to work together. Use the badge as one input, not the whole decision — ask the fit questions above regardless of tier.

Why confidentiality matters more than client logos

Most serious migration work happens under NDA — the brands moving platforms are usually established businesses that don't want their replatforming discussed publicly while it's happening, or afterward. An agency that can show you a wall of client logos and named case studies either works mostly with brands that don't mind public exposure, or is being looser with confidentiality than you'd want them to be with your own data. At UVT, every engagement is under NDA by default: we don't publish client names, logos or screenshots, and we describe case studies by sector, scale and stack rather than by identity. We'd rather be judged on the specificity of how we talk about the work than on logos we're not supposed to be showing anyone.

Frequently Asked Questions

What's the most important question to ask a Shopify migration agency?

How they handle SEO redirect mapping, specifically. It's the single most common way migrations lose organic traffic, and a vague or generic answer here is the clearest signal of how carefully an agency actually works.

Should I be worried if an agency can't show me client names or logos?

No — most serious migration work happens under NDA, and an agency that respects confidentiality for past clients is a good sign for how they'll treat your data. What matters is whether they can speak specifically and technically about your platform and scale, not whether they can name names.

Is a higher Shopify Partner tier always the better choice?

It's a real signal of track record and verified results, but tier alone doesn't guarantee fit for your specific project. Ask the fit questions — SEO process, post-launch plan, itemized quote — regardless of an agency's badge.

How do I compare quotes from different agencies fairly?

Ask each one for the same breakdown: data migration, development, integrations and QA as separate line items, not a single number. A lower lump-sum quote from an agency that hasn't scoped your catalogue specifically is worth less than a higher, itemized one from an agency that has.

What should be included after the migration launches?

At minimum: active monitoring of Search Console, checkout completion rate and support tickets for the first few weeks, and a clear, written understanding of whether post-launch fixes are included or billed as a new project. Get this in writing before signing, not after something goes wrong.
