Migration Guides
The migration, not the pitch.
Every migration proposal reads the same: less risk, more speed, a platform built for growth. What actually happens between kickoff and the first order on the new system is a different document, and most vendors skip it.
These guides are that document, one per migration path — the data-model mapping, the redirect strategy, the integrations nobody wrote down, and the cutover mechanics that keep the business selling through the move.
Why migrations fail
Four ways a migration loses money nobody budgeted for.
None of these are exotic. They are the same four shortcuts, taken to hit a date, on nearly every migration that goes wrong.
A date replaces a readiness bar
The team commits to a launch date before parity is proven, because the date was set months earlier. Real traffic hits an unproven system on a day nobody can undo.
Invisible integrations surface late
Tax, search, loyalty, and fulfillment logic lived inside the old platform without anyone documenting it, because it never had to be documented while the platform was working. It surfaces the week production traffic hits it.
SEO gets mapped from the sitemap
Orphaned pages and old campaign URLs carry real backlinks the sitemap never listed, because the sitemap only ever reflected the current site structure. They vanish, and organic traffic drops with them.
The rollback plan is a document
A slide with a rollback section is a hope, not a system, until someone has actually rehearsed it. If the old platform stopped taking orders the day the new one launched, there is nothing left to roll back to.
How we run it
Parallel run, not big bang.
This is the discipline behind every guide on this page, applied to whichever platform is actually leaving.
The old platform stays live
It keeps taking orders, staying current on catalog and pricing, through the entire build and parallel-run phase — not frozen the day the new build starts and left to drift out of sync.
Parity is proven lane by lane
Data, SEO, integrations, checkout, and operations each cross their own checkpoint before cutover, with a named owner and a pass/fail bar, not all judged together on launch day under pressure.
Rollback is a running system
The old platform stays rehearsed and ready to take traffic back, for as long as the team needs it — the decommission date gets set after cutover succeeds, never before, and never on faith.
Choosing the destination platform is Platform Migration. Keeping the estate and modernizing only its edges is Legacy Modernization. The guides below sit underneath both — the mechanics once the direction is picked.
