Years of SFMC experience
Navigating the technical hurdles that threaten your go-live
Revenue-killing downtime
Paused sends and broken schedules bleed revenue while teams scramble to fix unplanned interruptions.
Journeys rebuilt, not improved
One-to-one rebuilds preserve legacy flaws while adding new platform constraints.
Data extensions built wrong
Data extensions are often rebuilt with mismatched field types and broken relationships.
Deliverability drops after go-live
Launching without an IP warm-up or proper authentication resets your sender reputation.
Templates arrive but don't work
Static transfers break dynamic content and strip out AMPscript.
Testing that misses the real risks
Technical UAT confirms data exists, but ignores how it behaves. Silent errors only surface after sign-off.
A foolproof Salesforce Marketing Cloud migration that protects your revenue and your reputation
Lifecycle first, platform second
- Full customer lifecycle is mapped before any migration work begins
- SFMC architecture is designed around real entry points, triggers, and conversions
- Lifecycle is not forced into a pre-built platform structure
Campaigns stay live throughout
- All active campaigns are mapped before migration starts
- Send schedules are protected and maintained
- Suppression lists are validated at the source and migrated with full integrity checks
- Continuity of live revenue flows is ensured
Journeys audited before rebuild
- Every active journey is audited before migration
- Underperforming branches are redesigned, not replicated
- Subscribers already in-flight are preserved
- Entry criteria, wait steps, and splits are tested in a sandbox before go-live
Data built for segmentation, not just storage
- Data extensions are designed around the actual segmentation model
- Field types are aligned and relationships are mapped
- Engagement history is migrated and made queryable from the start
- Targeting is ensured to reflect real customer data.
Deliverability protected from the get-go
- IP warm-up is planned before go-live
- SPF, DKIM, and DMARC are configured and validated
- Sender reputation is benchmarked pre-migration
- Deliverability is built into the migration, not treated as a post-launch fix
Don't let a platform switch stop your momentum.
We manage the complex technical migration in the background so your revenue-driving campaigns stay live, your data stays intact, and your customers don't experience any disruption.

Frequently asked questions
How long does a Salesforce Marketing Cloud migration take?
A clean migration—single source platform, clear scope, no live campaign constraints—typically takes 6–10 weeks from audit to go-live. Timelines extend with complexity: multiple platforms, large journey libraries, high template volume, or always-on campaigns. The biggest delay driver is poor data quality discovered mid-migration. Our audit surfaces these issues upfront, helping clients go live faster.
What happens to our live campaigns during migration?
They run as usual. Every active campaign, send schedule, and suppression rule is mapped before migration begins. The transition is planned around your campaign calendar. Nothing goes live on the new platform without testing and sign-off. Subscribers experience no disruption.
What happens to journeys with subscribers already in them?
They are managed, not cut. Active journeys with in-flight subscribers are mapped and transitioned during the migration. Every subscriber follows a defined continuation or exit path; no one is dropped.
How do you protect deliverability after the platform switch?
Deliverability is planned before go-live. IP warm-up is scheduled in advance, and domain authentication (SPF, DKIM, DMARC) is fully configured and verified. Sender reputation is benchmarked pre-migration so any post-launch changes are measurable and recoverable. Most deliverability drops come from poor planning—we account for it upfront.
What happens to our email templates during a Salesforce Marketing Cloud migration?
Every template is audited—active, inactive, and duplicate. The library is streamlined before migration. Templates are rebuilt as modular Content Builder components with AMPscript and dynamic content—not lifted as static HTML. All templates are render-tested across 40+ clients before handover. Teams typically see ~30% faster campaign production from week one.
What do you audit before migrating to Salesforce?
We audit all critical components upfront to identify what needs to be rebuilt or updated before migration. This includes Visualforce pages and components, JavaScript buttons, S-controls, custom page layouts, reports and dashboards, workflow rules that need to be rebuilt as Flows, and API version compatibility.
Can you work alongside our internal Salesforce team?
Yes—this is the most common model. We work alongside your team, adding SFMC-specific migration expertise. Whether you need support with journey migration, template rebuilds, or Data Cloud architecture, we complement your internal capabilities.
Do you support post-migration once we're live?
Yes. Ongoing support can continue post-migration. Your team gets help with campaign execution, platform optimization, and technical support from day one after go-live.
