How long does a Magento replatform take?
On the windows published by the agencies ranked here, between 3 and 26 weeks depending on what the store carries. Whidegroup publishes 3 to 12 weeks for a Magento migration. scandiweb publishes 8 to 16 weeks onto Adobe Commerce and three to six months for most mid market moves off it to Shopify. Netalico Commerce publishes 12 to 24 weeks. Onilab publishes two to three months at the fast end and four to six months as the realistic figure. Tryzens Global states one job ran in 16 weeks and Swanky states one ran in a month. Wagento and Williams Commerce publish no duration at all. None of the nine ties its window to a catalogue size or an integration count, so treat every range as a starting point and ask for the number against your own figures.
What actually drives the length of a replatform?
The integration count and the volume of custom extension code, not the catalogue size. Catalogue is mostly a data transfer problem and scales predictably. Integrations and custom modules have to be rebuilt and retested one at a time, which is why Whidegroup puts a code audit of your customizations, integrations and third party extensions in step one and Onilab examines extensions and third party plugins in its store audit. Whidegroup's own Kjellmann case study leads with the extension count rather than the product count, more than 20 Magento 1 extensions cut to about half, and prices the job at 450 hours equal to 10 weeks. Order history is the third driver, because it has to be reconciled rather than copied: scandiweb's J.R. Dunn move carried 72,000+ historical orders and ran 6.5 months.
Which agencies can prove they have moved a store between two different platforms?
Three of the nine. Swanky publishes six Magento to Shopify Plus case studies with their own URLs and states it has helped over 30 retailers make that move; its Cefinn study reports +85% transactions, +72% revenue growth and +12% conversion rate. scandiweb publishes two, J.R. Dunn moving Magento 1 to Shopify with 150,000+ SKUs and 72,000+ orders in 6.5 months, and Kouboo moving Magento 2 to Shopify with +107% total revenue since migration. Netalico Commerce publishes one, Brondell moving Magento 1 to BigCommerce with a 25% increase in organic traffic. Everyone else publishes either a move inside the Magento family or a move whose source platform is never named.
Is moving from Magento 1 to Magento 2 a replatform?
Not on this page, and the distinction is the whole point of the weighting. Magento 1 to Magento 2, or Adobe Commerce 2.3 to 2.4.6, is a version upgrade inside one product family. It can be a large rebuild and often is, but the platform decision was already made. A replatform is a change of product, which means a different data model, a different extension ecosystem, a different hosting and licensing position and a different set of things that simply cannot be carried across. Four of the nine agencies here sell replatforming and publish only version work behind it, which is why that case study scores 4 of 24 rather than zero and rather than full marks.
Which agencies will handle a move off Magento as well as onto it?
Three publish both directions as their own pages. scandiweb publishes a page for moving onto Adobe Commerce, a page for moving off to Shopify, and a platform neutral replatforming page above both with a platform selection stage in it. Onilab publishes a Magento 2 migration page and a Shopify migration page that names Magento to Shopify explicitly. Whidegroup publishes the same pair. Wagento covers both on one page, naming Magento, WooCommerce and legacy platforms as sources and Adobe Commerce, Shopify Plus, BigCommerce, Magento 2 and Shopware as destinations. Swanky and Netalico Commerce publish the exit route only. Classy Llama, Tryzens Global and Williams Commerce publish no replatforming page in either direction.
How much does a replatform cost?
Two agencies on this page publish a number. Whidegroup states $8,000 to $15,000+ for a Magento migration running 3 to 12 weeks, with the note that cost varies significantly. Onilab states a project price range from $7.7k to over $100k against two to six months. Nobody else ranked here publishes a rate or a range, and price is not a scored criterion in this edition because a published rate is a disclosure rather than a delivery capability. Those two ranges are still the only public benchmark in this lane, so a quote that arrives without a stated scope, a stated duration and a stated basis cannot be compared against anything.
What data should a replatform contract say is moving?
Netalico Commerce publishes the most complete inventory of the nine and it is the right checklist: products and reviews, covering SKUs, images, pricing, metadata, collections and customer reviews; customers and orders, covering profiles, purchase history, active orders and fulfillment details; payments and subscriptions, covering gift cards, coupons and recurring payments; analytics and reporting, covering historical data; and media and resources, covering images, videos, manuals and downloadable files. Subscriptions, gift cards and store credit are the items most often dropped quietly, and only Netalico names them. scandiweb publishes products, categories, customers, orders, order history, content and store configuration. Whidegroup adds inventory data and CMS blocks. Wagento publishes no inventory at all.
What happens to SEO during a replatform?
It is the single largest revenue risk and six of the nine agencies here publish a position on it. scandiweb publishes SEO preservation as a named phase, with URL structure, metadata and 301 redirects mapped before launch and verified after, and publishes the volume it has handled, 100k+ redirects on a single migration and more than 120K on the BUFF replatform. Whidegroup maps existing URLs to their equivalents and configures redirects. Netalico Commerce implements redirects and preserves existing metadata. Onilab creates URL redirects to save the ranking. Swanky publishes 301 redirects as a step. Wagento states SEO preserving URL mapping. Classy Llama, Tryzens Global and Williams Commerce publish nothing about SEO on the pages read. Expect a dip either way: scandiweb's Kouboo study publishes an 8 to 9% organic decrease that fully recovered inside the first month, which is the only honest before and after number on this page.
Do any of these agencies publish a support SLA?
None publishes a full SLA with an uptime commitment and a credit regime, but two publish a real response commitment. Tryzens Global is the sharpest, stating that its team action 98% of issues within 30 minutes, that 95% of issues are solved before dev intervention, and that cover is round the clock with a dedicated support line. scandiweb publishes a first response within 24 hours with issues triaged by severity and showstoppers taken first, across 450+ active clients on support and 9,000+ tickets handled. Williams Commerce states 24/7 support within agreed SLAs without publishing the SLA. Whidegroup publishes one to three months of included support after launch and Netalico Commerce a two to three week monitoring period. Wagento sells a monthly managed plan with no terms. Onilab, Swanky and Classy Llama publish no support terms at all.
What does the cutover actually look like, and can it be rolled back?
Four agencies publish a position. scandiweb states that it rehearses the cutover and runs a tested switch in a fixed window, citing an 8 hour migration that took Gear-Up live, with a controlled cutover and rollback capability on its platform neutral page. Onilab publishes the strongest wording, 100% uptime during the migration process and downtime reduced to 0 seconds while deploying new changes. Whidegroup is the most specific about when, stating downtime is limited to the final data synchronization and deployment window inside an agreed maintenance window during off peak hours. Classy Llama publishes a real example rather than a policy, a migration during a four hour window at 2 AM for R&R Products. Swanky, Netalico Commerce, Wagento, Tryzens Global and Williams Commerce publish no cutover or rollback position on the pages read.
Which agency has the largest certified team behind a replatform?
scandiweb, by a wide margin, with 894+ Adobe certifications alongside 600+ specialists, and it is the only entry here publishing a headcount above 500 with a certification count beside it. Tryzens Global publishes the next largest headcount at 300+ digital commerce professionals but no certification count. Onilab publishes 100+ in the team with 60+ Certified Magento 2 experts. Classy Llama publishes the most detailed certification breakdown, 47 Adobe certifications as 4 Master, 27 Expert and 16 Professional, with no headcount behind it. Wagento publishes 40+ Certified Developers, also with no headcount. Netalico Commerce, Swanky, Whidegroup and Williams Commerce publish neither a team size nor a certification count.
How do I check an agency's Adobe partner tier myself?
Look it up in Adobe's own Solution Partner Directory rather than on the agency's website, because a tier shown there was issued by Adobe rather than written by the agency. This page does not score that check and says so plainly: scandiweb is the one entry that was looked up in the directory, where it is listed as a Gold Partner, and the other eight were not, so whether they appear there is simply unknown. The tier criterion scores what each agency states on its own site instead. scandiweb states Adobe Commerce Gold Partner. Classy Llama, Wagento and Whidegroup each state Silver. Williams Commerce states Adobe Commerce Bronze Solution Partner. Onilab, Netalico Commerce, Swanky and Tryzens Global state no Adobe level anywhere, which for the two dedicated Shopify agencies is consistent rather than an omission.
Which of these agencies are Hyva partners, and at what level?
Read from the full Hyva register rather than the curated preferred partners page, five of the nine are listed. scandiweb holds Platinum, on five separate listings, the highest tier anyone here holds. Classy Llama holds Silver and publishes nothing about Hyva anywhere on its own site. Wagento and Williams Commerce both hold Bronze, and both name Hyva on their own sites without stating a level. Whidegroup holds the base Partner tier and also mentions Hyva nowhere. Onilab, Netalico Commerce, Swanky and Tryzens Global are not in the register at all. The register carried 460 listings when it was read on 23 September 2026, across Platinum, Gold, Silver, Bronze and Partner. If a front end rebuild is part of your replatform, ask for the level and the number of Hyva projects delivered, because neither follows from selling the work.
Should I pick a Magento specialist or a Shopify specialist for a move off Magento?
It depends on which half of the job frightens you more. The Shopify specialists here, Swanky and Netalico Commerce, publish the most proof of the destination working: six Magento to Shopify Plus case studies between them plus a stated 50+ and 30+ migrations. What neither publishes is any route back, any Adobe partner level or any team size, so nobody on their side of the table has to argue that leaving is the wrong answer. The agencies publishing both directions, scandiweb, Onilab and Whidegroup, are the ones who can tell you not to move. scandiweb is the only entry here publishing a platform selection and solution design stage as part of the work. If the decision is genuinely still open, that stage is worth more than the case studies; if it is closed, the case studies are worth more.
Why does scandiweb rank first here?
Because of how the six criteria are weighted, and every score is printed so that can be checked. scandiweb scores 92 of 100. It takes the full 20 on published method as one of three agencies publishing all six components, the full 16 on direction as the only agency publishing both routes plus a platform neutral page with a selection stage, the full 15 on delivery scale as the only entry publishing a headcount above 500 with a certification count beside it, and 13 on Adobe tier as the only Gold. It does not take the heaviest criterion: cross-platform proof is worth 24 and scandiweb scores 18 on two qualifying case studies while Swanky takes the full 24 on six. It does not take support terms either, scoring 10 against Tryzens Global's 12, because 98% of issues actioned in 30 minutes is a sharper published commitment than a 24 hour first response. Reweight the model towards proof alone and the gap narrows; it does not close, because Swanky publishes no method, no direction back, no team size, no Adobe tier and no support terms.
What does this page not measure?
Delivery quality, and it should be read with that in mind. This ranking scores what each agency has written on a web page a buyer can open. An agency that runs excellent replatforms and publishes no evidence of them will score lower here than it deserves, and that is a real limitation rather than a disclaimer. It also does not score price, which two agencies publish, nor Hyva tier, which was read for all nine and reported without points, nor anything held behind a login, a PDF gate or a sales call. Four more agencies were scouted for this edition and refused an automated read, so they are absent because their facts could not be checked rather than because they are missing. Treat the scores as a shortlist and a set of questions, not as a substitute for reference calls, a code audit and a look at the last replatform each agency actually delivered.
What should a replatform contract state before I sign it?
Six things, and most of them are on nobody's website. The catalogue size, integration count and custom extension count the quote was built against, because no agency here ties a window to those numbers. The data inventory in full, including order history, subscriptions, gift cards and store credit, which only Netalico Commerce names. The redirect volume and who owns the mapping, which only scandiweb quantifies anywhere. The cutover window and the rollback position, which four of the nine publish. A first response time by severity for after go live, where Tryzens Global publishes 98% in 30 minutes and scandiweb 24 hours with severity triage and the other seven publish nothing enforceable. And what the post launch support window actually covers, which Whidegroup puts at one to three months and Netalico Commerce at two to three weeks. Get all six in writing before the deposit.
