From Legacy SharePoint to Power Apps: How We Enabled a Low-Code Digital Transformation

In today’s fast-paced business environment, relying on outdated custom applications can hold organizations back—especially when those systems struggle to keep up with evolving technology and user expectations.

At Sujosu Technology, we recently helped a client transition from a legacy SharePoint-based application to a modern, mobile-ready solution using Microsoft Power Apps. The results? Faster performance, reduced IT overhead, and a more empowered workforce.

This blog explores the challenges the client faced, how our team approached the transformation, and the tangible impact of embracing the Power Platform.

The Challenge: Legacy SharePoint App That Couldn't Scale

Our client had long relied on a custom SharePoint application to manage internal workflows and data submissions. However, as the company grew and Microsoft rolled out platform updates, the app became a bottleneck instead of a business enabler.

Key problems included:

• Frequent app failures after SharePoint updates

  Even small changes in the SharePoint environment caused unexpected breakdowns, requiring external developer support.

• Poor mobile experience for field teams

  Employees using tablets and smartphones found the app hard to use, impacting data collection and productivity on the go.

• Sluggish performance with larger datasets

  Over time, increasing data volume led to delays, affecting approval cycles and reporting.

• High support and maintenance costs

  Every minor enhancement involved custom code, slowing turnaround times and stretching budgets.

• Compliance and audit risks

  The custom architecture lacked standardized security features, complicating audits and governance.

This legacy SharePoint solution had become a maintenance-heavy liability, limiting the organization’s ability to innovate and scale.

The Solution: Migrating to Microsoft Power Apps for Agility and Scalability

After a comprehensive assessment of the client’s needs and long-term digital roadmap, we recommended rebuilding the application using Microsoft Power Apps, a modern low-code platform built for agility, security, and seamless Microsoft 365 integration.

Here’s how Sujosu delivered value through this migration:

• Rebuilt application with a responsive Power Apps interface

  We re-engineered the solution to support clean design, faster performance, and intuitive user interactions.

• Mobile-friendly by default

  Power Apps supports responsive layouts and adaptive design, enabling field teams to access the app without any special configuration.

• Workflow automation with Power Automate

  Key actions such as approvals, alerts, and data synchronization were automated, improving speed and reducing manual errors.

• Empowered internal teams

  Non-technical users can now make updates or enhancements without depending entirely on developers.

• Strengthened security and compliance

  With built-in integration to Azure Active Directory, role-based permissions, and Data Loss Prevention (DLP) policies, the new app meets modern compliance standards.

  
  

The Results: Immediate Business Impact

The transformation was completed in just a few weeks. Here’s what the client experienced post-migration:

• 40% reduction in IT support tickets

• Faster data entry and workflow processing

• Seamless mobile access for distributed teams

• Lower ongoing maintenance and support costs

• Higher user adoption and satisfaction

This was more than a technical upgrade—it was a step toward operational efficiency and digital maturity.

Why Power Apps Is the Right Move for Legacy SharePoint Users

For businesses still tied to outdated SharePoint custom applications, the shift to Microsoft Power Platform—specifically Power Apps and Power Automate—offers a scalable, secure, and cost-effective alternative.

The benefits include:

• Low-code flexibility for faster solution development

• Native integration with Microsoft 365, Teams, Excel, and SharePoint

• Improved governance and compliance through centralized management

• Cross-device compatibility for today’s hybrid workforce

At Sujosu, we specialize in helping organizations unlock the true potential of their data and workflows by moving away from legacy systems.
