Fixed-bid, slice-by-slice migration from legacy stacks to modern architecture. You pay per verified handoff — not for promises.
The team that built the legacy system left. When you bring in a new vendor, they bill discovery hours before writing any migration code, and every timeline estimate carries its own uncertainty premium.
Traditional engagements deliver everything at the end. When something is wrong (and it always is), you are months in and either pay to fix it or go live with gaps that hit your customers directly.
Migrations often succeed in staging but fail the moment real data flows through. Without parallel-run verification against production traffic patterns, cutover becomes a guess.
We run an automated scan against your codebase to map the migration surface: endpoints, data-model complexity, external dependencies. You get a one-page summary within 48 hours. No strings, no sales call unless you ask.
We break the migration into vertical slices (e.g., "user auth + profile," then "order history," then "search"). Each slice is independently testable. You see it working before we move to the next one.
When slices are ready, we run your legacy and migration in parallel for a verification window. Any divergence is caught before cutover, and the handoff package includes the comparison data so you can verify yourself.
Archive of the scanned codebase, migration scripts with inline comments, an architecture comparison report, and a 2-week support window for questions. Your team runs it — we are only on call if things break.
Describe any legacy system and the demo below renders the structure of the one-page readiness summary you would receive: a 0–100 readiness score, a 12-category risk breakdown, the top 3 migration risks, and an estimated complexity tier. It runs entirely in your browser — deterministic, so the same description gives the same structure.
Runs fully in-browser; nothing is sent or stored. If the embed does not load, open sample.html directly.
The traditional agency model bills by the hour against a timeline that usually extends — and most quoted migrations run 40–60% over. We price a fixed bid for a mid-team framework swap and verify each slice before the next one starts. The exact bid for your system is scoped after the free scan.
One-page summary of your migration surface and top risks within 48 hours. No commitment, no sales call.
Base fixed bid for a mid-team framework swap, sliced and verified. Your exact bid is scoped in writing after the scan [A-1].
Optional 30-day support extension after the included 2-week window: regression fixes, architecture clarification, and on-call availability [A-2].
If you have seen an EOL announcement for any dependency in your stack, a readiness scan takes zero engineering time on your end. You get the one-page summary regardless. The scan cannot hurt; the only way it helps is by giving you early warning.
That is exactly why the parallel-run verification step exists. We will not declare a slice verified until it matches — and that verification is recorded in your handoff package before we move on to the next slice.
Yes — our sample proposal (a legacy PHP/Laravel commerce app migrated to a modern stack) shows the full pricing breakdown and slice-by-slice plan. It is available on request, and the demo above shows the structure of the free scan.
We will tell you that upfront. Greenfield is the wrong use case for this service — that is what our installer and rescue doors are for. If it makes sense, we scope it; if not, we pass.
It is a deliberate pricing judgment: a fixed, verifiable bid removes the uncertainty premium that makes agency migrations run 40–60% over quote. The base figure is an internal pricing anchor [A-1], not a market benchmark — we are happy to walk through the arithmetic on any sample proposal.
Share your repo or just tell us your tech stack. We run the scan and send you a one-page summary in under 48 hours — no sales call, no commitment. Or run the demo above first to see exactly what you would get.

This page is a demo storefront (prototype #4 in hermesbuilds). The live purchase channel is the Migrator Upwork listing — orders, intake, and delivery run through that listing until this surface goes live.
No performance-history claims are made. The value is the method: a fixed bid you can verify slice by slice, and a handoff your team runs itself. [O-12]
