Replatform commerce without losing a selling day
The most expensive ecommerce migration is the one that dents a trading quarter. We modernize commerce platforms in phases that protect revenue — proving conversion, speed and integrations at every step before anything old is switched off.

Why this is on your agenda
Why commerce modernization is different
An ecommerce platform migration runs on a live revenue stream. Every phase happens while customers shop, campaigns run and peak seasons approach — there is no maintenance window long enough to hide in. The graveyard of failed replatforms is full of projects that were technically fine and commercially catastrophic.
Done right, modernization is phased around the trading calendar, measured against conversion and speed baselines at every step, and reversible until proven. Composable and headless architectures earn their place where they unlock real velocity — not as fashion — and the old platform stays alive until the new one has beaten it in production.

- Composable is a choice, not a defaultHeadless pays off in specific conditions — and costs in all of them.
Key business challenges
Where commerce migrations go wrong
-
The big-bang cutover bets a quarter
Single-weekend migrations put SEO, conversion and integrations at risk simultaneously — and discover problems with revenue on the line.
-
Conversion regressions ship unnoticed
The new platform launches without baseline comparisons, and a quiet checkout regression eats margin for months.
-
SEO equity evaporates in the move
URL structures, redirects and metadata handled as an afterthought turn organic traffic into a casualty.
-
Integrations multiply the migration
Payments, tax, OMS, fulfillment, search and marketing tools each need their own migration — usually discovered mid-project.
-
Replatforming and peak season collide
Projects scoped in spring meet November reality; without calendar-aware phasing, the business chooses between the project and the season.
-
The team can't run what gets built
A modern stack lands without the operational skills and monitoring to keep it fast and stable.
The Cosmonaut approach
From risky rewrite to phased, proven migration
The same revenue stream — modernized in reversible phases, measured against baselines, timed to the trading calendar.
- One cutover date carrying all the risk
- No conversion or speed baselines to compare
- SEO and redirects handled last
- Integration scope discovered mid-flight
- Peak season treated as an inconvenience
- Phases sized to be reversible and provable
- Every phase measured against trading baselines
- SEO migration planned before the first move
- Integration map complete before sequencing
- The calendar shaping the plan, not fighting it

Where to go deeper
Questions technology leaders ask
Before you commit budget
Should we go headless or composable?
Only if your constraints justify it: multi-channel reach, front-end velocity bottlenecks, or platform limits you've actually hit. The assessment answers this with evidence — and a well-run monolith is sometimes the honest recommendation.
How do you protect revenue during migration?
Phases run in parallel with the old platform, each gated on beating baseline conversion and speed measurements before cutover, each reversible if evidence says stop. The trading calendar shapes the sequence.
What happens to our SEO rankings?
SEO migration is planned before the first phase: URL mapping, redirects, metadata and sitemap continuity — then monitored through every cutover so drops are caught in days, not quarters.
Can you work with our existing agency or team?
Yes — the standard model. We typically own architecture, migration engineering and measurement while your team and agency keep trading and building.
What does a discovery workshop involve?
A structured session with digital and engineering leadership: we map the platform, integrations and calendar constraints, and leave you a prioritized findings summary you keep.
Start with a discovery workshop, not a contract
One structured session with your platform and delivery owners produces a prioritized findings summary you keep — whether or not we work together afterward.
