Portmux is the platform-agnostic data migration service for teams switching CRMs, ERPs, databases, and SaaS platforms, without the hand-coded scripts, the downtime, or the data loss. Salesforce to HubSpot. NetSuite to QuickBooks. Any system to any system.
The market is moving away from off-the-shelf stacks. Teams are building their own platforms, their own tools, their own competitive moats. But every custom build hits the same wall: how do we get our data in?
Portmux embeds into your architecture. We expose an SDK, an API, and a webhook layer so your engineers can treat data ingestion from any source as a solved problem, not a six-month side quest.
You built a better CRM / support tool / ERP. Now you need 5 years of customer data out of the old system and into yours, every field, relationship, and attachment intact.
Your product aggregates data from your customers' systems. Portmux becomes your integration layer, pre-built connectors, normalized schemas, an SDK your devs own.
PE portfolio bought three firms on three different stacks. Consolidate every tenant into the winning system, SaaS or custom-built.
A mainframe, a Lotus Notes install, a FoxPro database. Portmux extracts, transforms, and routes into your modern stack, no COBOL expertise required.
A read-only connector indexes the source, SaaS or custom, generates a schema map, and flags every custom field, attachment, and relationship.
Our engineers draft a field-level mapping document, including custom adapters for proprietary schemas. You approve it before a single record is written.
Dual-write staging keeps both systems in sync during rehearsal. On cutover day, we flip traffic to the destination. Your team keeps building.
Salesforce, NetSuite, Zendesk, Shopify, Jira (most systems with an API or a documented export), migrated into the platform your team is building. We work alongside your engineers, version-pin the destination contract, and hand off the migration code in your stack.
Every step we run before, during, and after a production cutover.
Real numbers from real engagements. The four pricing models, what each one hides, and how to scope honestly.
CDC, dual-writes, and the cutover patterns that let you switch platforms without a maintenance window.
Why ERP migrations fail, what changes between SAP, NetSuite, and QuickBooks, and how to phase a 12-month rollout.
Schema drift, character encoding, foreign-key fan-out, audit gaps. The failures we plan around on every engagement.
Portmux handles PHI, PII, financial records, and export-controlled data every day. Our controls go beyond checkbox compliance.
AES-256 at rest. TLS 1.3 + mTLS in transit. Customer-managed keys on request.
US, EU, UK, APAC deployment zones. HIPAA BAAs, GDPR DPAs on file.
Time-boxed, ticket-bound access with full session recording.
Row-level reconciliation report delivered at go-live and archived for 7 years.
Single-system migrations (Track A) typically run 4–6 weeks from kickoff to cutover. Multi-system consolidations (Track B) run 8–12 weeks. Enterprise and M&A migrations (Track C) run 12+ weeks. The pace is set by your team's availability for mapping review, not by our engineering throughput.
Yes. Salesforce to HubSpot is one of our most common CRM migration paths. We handle contacts, companies, deals, custom objects, attachments, and activity history with full field-level mapping and zero data loss. We also support HubSpot to Salesforce, Pipedrive, Zoho, and Microsoft Dynamics migrations.
Nothing dramatic. We use a zero-downtime cutover approach with dual-write staging. Both systems stay in sync during a rehearsal window. At the scheduled time we flip your application traffic, run a final reconciliation pass, and sign off. Your end users don't experience a freeze.
Single-system switches start from $12K. Multi-system consolidations start from $38K. Enterprise and M&A migrations are custom-quoted. Final price depends on object volume, custom field count, and integration complexity. We scope it on a 20-minute call before any commitment, no hourly billing.
We build it. Custom connector development is scoped into your engagement, typically 1–3 weeks of additional lead time. Any system with an API, a database driver, or a structured file export is fair game. We've migrated data from legacy mainframes, FoxPro databases, and flat-file SFTP drops.
Yes. Track B and C customers can license the Portmux engine post-engagement for ongoing data sync, divestiture events, or future tenant migrations. Ask about Portmux Rails, our self-serve migration platform for repeat movers.
The source system stays authoritative until you sign off on reconciliation. During the rollback window (30 or 90 days depending on track) we maintain a hot-standby that can be re-promoted in under an hour. Every record is accounted for in a row-level reconciliation report.
