Scalability is the lifeblood of SaaS, but legacy infrastructure is often the bottleneck. Our client — a global leader in purchase-to-pay solutions — hit a hard wall. Their sales teams wanted to run, but a fractured data landscape forced them to crawl. Insights stalled. Decisions lagged. Leadership realized that patching the old system was a dead end. To truly unlock global growth, they committed to a comprehensive Microsoft Dynamics to Salesforce migration.
But swapping out a company’s central nervous system is never simple. Before we could execute our record-breaking 8-hour data cutover, we had to untangle a complex web of manual roadblocks.
The Challenge
When Legacy Infrastructure Stifles Growth
Agility defines scale. But this client was stuck. Technical debt weighed them down.
Their existing SaaS CRM implementation was fragmented. Critical customer data sat trapped in an aging Microsoft Dynamics environment, making it impossible to act as a modern SaaS revenue operations platform. These disparate systems created three major problems:
- Siloed Reporting: Leaders had blind spots. There was no “single source of truth” for accounts or pipelines.
- Security Risks: Access was too open. Everyone saw everything, which failed to meet modern compliance standards required for fintech sales stack integration.
- Manual Overload: Sales reps wasted time. They duplicated work across online and offline tools instead of closing deals.
The goal was clear — build a unified Lead-to-Revenue architecture on Salesforce Sales Cloud (now known as Agentforce Sales). But the complexity of a Microsoft Dynamics to Salesforce migration is scary. Most enterprises fear data loss and long periods of downtime.
The Solution
A Unified Salesforce Lead-to-Cash Transformation
A5 accepted the challenge. We didn’t just migrate the data; we transformed the business logic to ensure a scalable CRM architecture for SaaS.
The 8-Hour Cutover with Talend Data Integration
We utilized Talend data integration for high-velocity transfer. Our team migrated 19 connected jobs at once. Standard projects take weeks, but we finished in an 8-hour window. The result? A no-downtime legacy system transition for global sales.
Unified Quote-to-Cash (Q2C) Solution
We connected the dots immediately. The new Sales Cloud environment integrated instantly with HubSpot, Gainsight, SAP CPQ, and D&B. This created a truly Unified Quote-to-Cash (Q2C) solution, eliminating the gaps between marketing, sales, and finance.
Future-Proofing for End-to-End Sales Process Automation
We built a two-level account hierarchy. Now, when new customers enter the system, the data stays clean. No manual cleanup required — just pure end-to-end sales process automation.
Why It Worked
Orchestrating a Zero-Disruption CRM Migration
Why did this succeed? Because we treated data migration as a strategic operation, not an IT ticket. A successful Microsoft Dynamics to Salesforce migration requires more than just moving records.
We Mapped Logic, Not Just Data
Microsoft Dynamics and Salesforce speak different languages. We didn’t just “lift and shift.” We re-architected the model to support complex assignment logic, ensuring a Salesforce L2C implementation that actually fit the client’s business model.
The "Staging" Strategy for a Risk-Free CRM Go-Live
We tested everything first. By building a robust staging environment, we validated 100% of the data integrity before the switch. This allowed us to execute a seamless data cutover on launch day.
User-Centric Design
Systems need users. We built automations to “celebrate wins” and renewals. The new system felt like an upgrade, driving immediate adoption.
“Moving from Dynamics to Salesforce is historically one of the most friction-heavy migrations in the SaaS industry. It usually involves weeks of data cleaning post-go-live. The fact that this project achieved a clean, 19-job cutover in a single 8-hour shift is a masterclass in data orchestration.”
