Magento Migration Without Losing Orders, Customers Or Rankings

Four things, in rough order of impact. How much custom code the old store carries, since every custom module is a rebuild decision rather than a copy. How clean the data is, because a catalog with duplicate SKUs and inconsistent attributes costs more to move than a tidy one of the same size. How many integrations have to be reconnected and retested, each of which is its own small project. And how much of the theme is rebuilt rather than adopted. Catalog size on its own matters far less than people expect: a large clean catalog is cheaper to move than a small messy one.

We keep it running and reachable for a defined period rather than switching it off at cutover, because it is your rollback path until the new store has proven itself under real traffic. After that it becomes an archive question rather than an operational one. You will want historical order and customer records retained for tax and legal purposes, which usually means a database export held somewhere safe rather than a live server you keep paying for. We agree that retention period up front and say what can be decommissioned once it passes, since an old store left online is an unpatched security exposure.

Fewer people than you might think, but three roles have to exist. Somebody who can decide about catalog and content without escalating, because dozens of small questions come up during data mapping and waiting on each one is what stretches a schedule. Somebody who knows your integrations, or at least holds the accounts and credentials for them. And somebody commercial who can approve the cutover window. Beyond that we need your team for testing at the end, particularly on checkout and anything unusual about how you sell, since they will spot wrong behavior far faster than we can.

Products, categories, attributes and images, customer accounts and address books, complete order history with invoices and credit memos, CMS pages and static blocks, promotions and coupon rules, product reviews and ratings, SEO URLs and metadata, plus multi-store, tax and shipping configuration. Every data type is reconciled against source counts before cutover is even discussed. A migration is also a rare chance to leave things behind. Expired coupons, disabled products nobody will re-enable and test customers from years ago can be dropped, and we flag those rather than carrying the clutter forward.

Yes. Replatforming to Magento 2 from another cart follows the same discipline as a Magento 1 migration: audit the source store, map its data model onto Magento attribute sets, migrate in scripted dry runs, rebuild the theme and integrations, and cut over with a full 301 redirect map. It is the right move when multi-store, B2B pricing or catalog scale has outgrown the current platform. It is the wrong move when the current platform is simply slow or badly built, since that tends to follow you across, and we will say so.

Magento 1 extensions do not run on Magento 2, so each is mapped during planning to one of three outcomes: a native Magento 2 feature that replaces it, a maintained marketplace equivalent, or a scoped custom build where the functionality is business-critical and has no substitute. You see and approve that mapping before migration starts, so nothing silently disappears. There is usually a fourth outcome too. On most Magento 1 stores a meaningful share of installed extensions turn out to be unused, and retiring those is the cheapest decision in the whole project.

Customer accounts, addresses and order history migrate fully. For Magento 1 to Magento 2 moves the password hashes are migrated and upgraded transparently, so customers log in with their existing passwords. When replatforming from other carts, portability depends on how the source stored them, and where hashes cannot be carried we set up a smooth one-time reset flow instead of losing the accounts. Where a reset is unavoidable we plan the communication in advance, because customers who meet an unexplained login failure on a relaunched store often simply leave.

Three mechanisms. A content freeze pauses catalog changes at an agreed time. A final delta sync copies every order and customer created since the last full migration run. Record counts are then reconciled between the old and new databases before DNS switches. Orders placed during the build window are captured by the delta sync rather than abandoned. The freeze is the part that needs your team's agreement rather than ours, since it means no catalog edits for a defined period, and it is far easier to arrange with a week of notice.

The full data migration is executed on a staging copy exactly as it will run for real: same scripts, same mapping rules, same order of operations. The result is tested, problems are fixed in the scripts, the staging target is wiped and the run repeated until it completes cleanly. The production run is then a repeat of something that has already succeeded rather than a first attempt. Fixing the scripts rather than the migrated data is the discipline that makes this work, because a hand-corrected result cannot be reproduced on the day.

Yes, and infrastructure moves are a service in their own right, covered in detail on our Magento server configuration and migration page. In short, the environment is rebuilt on the new infrastructure with the web server, caching, search and database tuned for Magento, files and database are synced, the store is tested privately on the new server, then DNS switches in a low-traffic window with the old server held as rollback. It is a far shorter engagement than a platform migration, because nothing about the application itself changes.

Every migration includes 2 to 4 weeks of post-launch care: 404 and error monitoring, Search Console checks, performance tuning and rapid fixes for anything QA did not catch. After that you can continue with an ongoing Magento support retainer staffed by the same engineers who ran the migration, or hand over to your own team with full documentation. The 404 monitoring matters most in that period, since it is the fastest way to find redirect gaps testing missed, using real inbound traffic rather than a predicted list of URLs.
