Multi-Million Dollar CRM Migration

Case Study • Published 2025

Back to Case Studies

Overview

A mid-market company with a multi-million dollar sales operation was struggling with a custom-built PHP CRM system that was becoming increasingly unreliable and difficult to maintain. The system, built years ago, was causing daily frustrations for the sales team and providing limited visibility for leadership into sales performance and pipeline health.

ByteBlaze was brought in to migrate the entire sales operation from the legacy custom PHP CRM to HubSpot, ensuring zero downtime, complete data integrity, and improved functionality for both sales staff and leadership.

The Challenge

Critical Issues with Legacy System

The company needed a solution that would not only replace the existing system but also provide enhanced capabilities for sales operations and business intelligence.

1. Discovery and Planning

We began with a comprehensive analysis of the existing system:

2. HubSpot Configuration

We configured HubSpot to match and improve upon existing workflows:

3. Data Migration

The most critical phase was migrating years of sales data:

4. Training and Support

We ensured smooth adoption through comprehensive training:

Results

Improved Reliability

99.9% uptime—HubSpot's cloud infrastructure eliminated the frequent crashes and downtime that plagued the custom system. Sales staff could work without interruption.

Increased Efficiency

30% reduction in administrative time—Sales staff reported spending significantly less time on data entry and system navigation. Automated workflows handled routine tasks, allowing salespeople to focus on selling.

Enhanced Visibility

Real-time analytics and reporting—Leadership gained immediate access to comprehensive dashboards showing pipeline health, conversion rates, sales forecasts, and team performance metrics. This enabled data-driven decision making.

Better User Experience

Modern, intuitive interface—Sales staff found HubSpot's interface significantly more user-friendly than the legacy system. Mobile access allowed them to update records and respond to leads from anywhere.

Lessons Learned

This migration taught us several important lessons:

1. Thorough Discovery is Critical

Taking time upfront to understand all system dependencies and user workflows prevented issues during migration and ensured nothing was missed.

2. User Training is Essential

Even the best system fails if users don't know how to use it. Comprehensive training and ongoing support ensured smooth adoption.

3. Data Quality Matters

Cleaning and normalizing data during migration improved data quality in the new system, leading to better analytics and reporting.

4. Phased Approach Reduces Risk

By testing migrations and executing in phases, we minimized risk and ensured data integrity throughout the process.

Conclusion

The migration from the custom PHP CRM to HubSpot was a complete success. The company now has a reliable, modern CRM system that improves efficiency for sales staff and provides leadership with the visibility and analytics they need to make informed decisions.

The result: A more productive sales team, better-informed leadership, and a scalable CRM solution that will support the company's growth for years to come.
