Integration migration services that replace failing middleware without breaking order flow
Your connectors were built for a smaller business. Migrating integration by integration, we move every sync, mapping, and workflow to a stack you own. Validated in parallel, switched with zero downtime.

A dying integration layer charges rent every single day
Nobody budgets for the middleware that quietly stopped scaling. Integration replacement services exist because the cost shows up as people, not invoices: re-keyed orders, stale inventory, and a support queue full of "where is my order".
Life with legacy middleware
- Syncs fail overnight and someone re-enters orders by hand the next morning.
- Inventory updates lag by hours, so the storefront sells stock the warehouse no longer has.
- The vendor ended support, and the one person who understood the configuration left in 2023.
- Every new system you add needs a fragile workaround because the old layer cannot connect to it.
- License renewals climb while reliability falls, and nobody can explain what you are paying for.
Life after replacement
- Orders, inventory, and customers move in near real time across every connected system.
- Failures alert your team in minutes with the exact record and field that broke, then retry on their own.
- Every mapping is documented, so any developer can maintain the stack, not just the one who built it.
- New systems plug into the same platform in days, with the same monitoring from day one.
- You own the credentials, the code, and the platform contract. No partner lock-in, ever.
Middleware migration services close that gap in weeks, not quarters. The section below shows exactly what changes.
One stack before. One stack after.
This is the shape of a typical integration platform migration: the same five systems, the same data flows, a completely different failure profile.
Legacy middleware
Vendor support ended · undocumented mappings · nightly batch only
Every flow passes through one fragile, unsupported hub.
Modern integration platform
Event driven · documented mappings · monitored with alerting · owned by you
Same systems, rebuilt flows, automatic retries, full audit trail.
Everything our integration migration services include
You receive a working replacement, not a recommendation deck. Each line below is a deliverable you keep, whether or not we ever work together again.
Integration audit and dependency map
Every connection, schedule, and hidden script catalogued before anything moves, so nothing gets orphaned mid-migration.
Field-level data mapping sheets
Source field to target field, transformation rules, and edge cases documented in plain language your team can review and approve.
Rebuilt flows on a platform you own
Connections rebuilt as integration replacement services should be: event driven where possible, in your account, under your credentials.
Parallel-run validation
Old and new flows process the same live events side by side until outputs match record for record. Cutover happens only after proof.
Zero-downtime cutover and decommission
Traffic switches one connection at a time in an approved window. The legacy layer stays available as rollback until you sign off, then it is retired cleanly.
Monitoring, alerting, and 30-day hypercare
Dashboards and alerts wired before go-live, plus 30 days of watch-and-fix support after the last connection moves.
Scoped before work starts · line-by-line pricing per connection · no commitment to receive a proposal.
From fragile to fully replaced in five phases
Our middleware migration services follow the same disciplined sequence on every engagement. Click any phase to see the deliverable it produces.
Connections discovered: 14
3 undocumented scripts found on the legacy server · flagged for mapping
212 fields mapped · 9 awaiting your approval
Retries, dead-letter queue, and alert routing enabled on every built flow
Cutover unlocks after 7 consecutive clean days
30-day hypercare begins the moment the last flow switches
14 connections moved, zero orders lost
Harbor Supply Company
Wholesale distributionHarbor Supply distributes industrial hardware to 2,300 trade accounts across three warehouses and two storefronts.
The problem
Their on-premise middleware lost vendor support, and nightly batch failures forced staff to re-key hundreds of orders a week. Adding a new marketplace channel was impossible on the old layer.
The solution and result
An 8-week integration platform migration rebuilt all 14 connections on a modern, monitored platform, validated through a 2-week parallel run before a phased cutover.
drop in failed syncs within the first month after cutover
11,400 orders per month now flow with zero manual re-entry, and the new marketplace channel launched 3 weeks after go-live.

What a typical partner skips, we put in the contract
Most integration replacement services quote a rebuild and hope the cutover goes well. Hope is not a migration plan.
- Parallel run is mandatory, not optional. No connection switches until live output matches record for record.
- Scope locked before build. Connection-by-connection pricing in the proposal, so the number you approve is the number you pay.
- You own everything. Platform account, credentials, code, and documentation are yours from week one. No partner lock-in.
- One team, full estate. The same engineers who run your migration also build new connections, so handoffs never drop context.

Integration migration, answered straight
Integration migration services move your existing system connections, such as order sync, inventory updates, and customer records, from an old middleware tool or custom scripts to a modern integration platform. The work covers auditing every current connection, rebuilding each one on the new platform, validating output side by side, and retiring the old layer only after the new one proves itself in production.
A typical integration platform migration covering 5 to 15 connections runs 4 to 10 weeks. The audit and mapping phase takes 1 to 2 weeks, the rebuild takes 2 to 5 weeks depending on connection count, and the parallel run plus cutover takes 1 to 3 weeks. Larger estates with 20 or more connections are phased so the highest-risk flows move first.
Yes. The new connections run in parallel with the old ones, processing the same live events into a staging target. We compare output record by record until the match rate holds at 100 percent for an agreed window. Only then does traffic switch, one connection at a time, during a low-volume window your team approves. The old layer stays available as a rollback path until you sign off.
Our middleware migration services cover aging on-premise tools such as Microsoft BizTalk Server, early integration platform as a service products that are losing vendor support, point-to-point custom scripts, scheduled file transfers, and no-code automation tools that were never built for your current order volume. If a connection moves data between two systems today, we can map it and rebuild it.
Cost depends on the number of connections, the depth of field mapping, and the validation window your operation needs, so we do not publish a flat rate. Every engagement is scoped before work starts, with line-by-line pricing for each connection, and there is no commitment required to receive a proposal. Submit a brief and you will have a scoped number within 3 business days.
Is this migration the right move for you?
Good fit for you if
- You run 3 or more live connections on middleware that is unsupported, undocumented, or failing.
- Order or data volume has outgrown what the current layer was built for, and growth is the plan.
- You want integration replacement services that end with your team owning the platform, not renting a black box.
Not a fit if
- You need a single one-time data export rather than ongoing, living connections between systems.
- The systems on both ends are also being replaced this quarter. Migrate the platforms first, then the integrations.
- You need everything switched inside one week. A safe parallel run cannot be compressed below its validation window.
