Migrate, and fix what moves with you
The platform is the constraint. We plan the migration, and the leaks the diagnosis found are fixed in the new build rather than copied into it.
For brands on WooCommerce, BigCommerce, Magento or a custom build, weighing a move to Shopify
A migration moves your leaks along with your products.
We migrate stores to Shopify and Shopify Plus. Before we do, we find what your current store is losing money on, so the move fixes it instead of carrying it across. Then we plan the migration around measurement, so you can see what changed.

Is it the platform, or what you built on it?
Usually some of each. The trouble is that both feel the same from the inside: everything is slow, every change costs a quote, and conversion has been sliding for a while. A migration fixes the first kind. It does nothing for the second.
Every change needs a developer
Merchandising edits, a new landing page, a test idea: each one goes into a queue, and the queue sets how fast you can learn.
The upgrade bill keeps coming
Version upgrades, security patches and extensions that break each other. Money spent keeping the store standing, none of it spent on selling.
Plugins are holding the checkout together
Several extensions doing one job each, and nobody sure which one would take the checkout down if it were switched off.
Conversion is sliding and the platform is the suspect
Maybe it is. But the platform is also the easiest thing to blame, because it is the one thing nobody on the team chose this year.
Migrate for the right reason, not the loudest one
Good reasons to move, and expensive ones.
Some reasons to migrate are sound. The platform blocks changes your business needs. Keeping it running costs more than it earns you. Its checkout, speed or app ecosystem caps what any amount of careful work can achieve. When that is what the evidence shows, moving is the honest answer, and the sooner the better.
Other reasons are expensive. Conversion dropped and someone said Shopify converts better. A competitor moved. An agency quoted a migration because it is the largest thing they can sell you.
The difference matters because a migration is a large project with real risk to search traffic, data and the buying path. If the reason for it is wrong, you pay all of that and keep the problem.
So we diagnose first, including when you arrive certain.
The part most migrations skip
Your leaks do not stay behind on the old platform.
A migration copies your products, customers, orders and pages. It also copies the reasons people leave without buying: the offer that is unclear in the first few seconds, the ad that lands on the wrong page, the product page that leaves sizing or shipping unanswered, the cart that surprises people with the total.
None of those are platform problems, and all of them arrive on Shopify intact. Moving them across without fixing them means paying for a new store that loses money the same way the old one did.
So the diagnosis looks at your whole buying path, the same nine places we check on every store, and decides which problems the migration will fix by itself, which need fixing during the move, and which are not worth touching yet.
Three honest outcomes
What the diagnosis can conclude.
Fix it where you are, for now
The constraint is in what was built, not in the platform. Fixing it costs less than moving and pays back sooner. If your team can implement, we work with them on your current platform.
DevelopmentMove later, on purpose
The case for Shopify is real but the timing is not: peak season is close, an integration is mid-project, or the data is not ready. You get a plan for when and how, instead of a rushed launch.
Whichever it is, you get the reasoning in writing, and the decision stays yours.
If migration is the answer
The parts of a migration that go wrong.
A replatform is mostly risk management. These are the things that quietly cost revenue when a migration is run to hit a launch date:
- URL structure and redirect mapping, so search traffic finds the new pages
- Analytics and tracking continuity, so the before and after can be compared
- Checkout, payment and tax configuration
- Subscription and recurring billing migration
- Customer, order and historical data integrity
- Customer accounts, and how people sign in after the move
- Third-party integrations and whatever depends on them
- Launch QA against the buying path, not just the page templates
We plan the migration backwards from measurement. A baseline is set on the old store before anything moves, so after launch you know whether the new one is doing better, and where it is not.
In order
Diagnose, decide, then move.
Diagnose
We look at your store, your analytics and your platform, and find what is costing you money and why. If you want a read from outside first, the $497 Revenue Leak Audit is delivered in 3 business days.
Decide
Migrate, fix in place, or move later, with the reasoning written down and the leaks ranked by what they cost.
Plan around measurement
A baseline on the old store, every URL mapped, every integration listed, and the leaks to fix in the new build scoped before the build starts.
Build and move
The Shopify or Shopify Plus build, the data migration and the integrations, with QA on the buying path before launch.
Measure what changed
The new store is compared with the old one on the same measures, so the migration has a result, not just a launch date.
The evidence
Three leaks, three measured outcomes.
Every result below names the change we made, the sample it was measured across, and the window it was measured over. Where we do not have a published result yet, we say that instead of filling the gap.
These are results from work on Shopify stores. A migration is worth it when it makes work like this possible.

Largest session sample in our test history. Conversion rate was the primary metric. Revenue per visitor rose 3%, which did not clear the decision threshold on its own.

Our longest test window. When the window matters more than the number, this is the one to read.
Projected monthly contribution is extrapolated from the test window. It is not revenue banked, and we will not present it as though it were.
Results are specific to the cited experiments. Not every test wins, and projected contribution depends on the measurement window and store economics.
Six of the nine leaks VASTA inspects do not yet have a published result behind them. Those are described as process, not proof, until a proof pack exists. How we measure
The VASTA agreement
Agency fatigue is earned. These are the boundaries.
- No diagnosis, no pitch.
- No proof, no public claim.
- No scope creep disguised as strategy.
- No-fit means no forced sale.
And no migration we cannot justify with what the diagnosis found.
This works when the move is worth getting right.
Likely a fit
- You run on another platform with meaningful traffic and revenue
- The platform is visibly slowing you down, or costing you to keep it standing
- You want the move decided and planned on evidence
- You will keep measuring through the migration and after it
Probably not a fit
- You want to be on Shopify by a date, whatever the evidence shows
- You are looking for the cheapest available migration
- You are pre-revenue, or too early for the investment to make sense
- You are unwilling to set a baseline before anything moves
Also a fit. Staying on your platform and want the diagnosis and the testing strategy for your own team to implement? You can still qualify.
Before you talk to us.
We can, after the diagnosis. If it confirms the move, you get a scoped plan with the evidence behind it and the leaks to fix in the new build. If it does not, you have kept the cost of the migration and found what is really costing you money.
Some movement after a migration is normal while search engines re-crawl the new store. What decides how much is whether every old URL redirects to the right new one, whether content and metadata come across intact, and whether anyone is watching search traffic after launch. All three are part of the plan, and none of them is left to launch week.
Products, collections, customers, orders and content, with integrity checks before launch. Subscriptions, customer accounts and integrations each get their own plan, because each behaves differently on Shopify.
It depends on the size of the catalogue, the number of integrations and the state of the data, so it is scoped after the diagnosis rather than promised up front. The diagnosis itself happens inside a Profit Sprint, which runs 21 days.
Yes. Shopify and Shopify Plus are our deepest implementation specialty.
Then we say so, with the reasons. If your team can implement, we can work with them on your current platform on diagnosis and testing.
The migration is scoped and priced after the diagnosis, because the honest price depends on what the diagnosis finds.
