For years, professional services firms have relied on Intapp Integration Builder (IB) to automate workflows and connect key systems across their IT landscape. IB provided the basic tools needed to manage data integrations between platforms like CRM, ERP, time management, and DMS. But the growth in data complexity, the shift to cloud-based applications, and the rising demand for real-time connectivity have exposed critical limitations in IB.
Imagine you’re managing a law firm with offices across the globe. Your client data resides in Salesforce, financials are stored in NetSuite, documents are archived in iManage, and timekeeping is managed in Intapp Time. The glue that binds these systems is Integration Builder, but it’s struggling to keep up. Updates are manual, troubleshooting is painful, and cloud integration is more of a workaround than a strategy. This scenario is not uncommon.
Enter Intapp Integration Service (IIS): a cloud-native, low-code platform built on Boomi that redefines what’s possible with system integration. With IIS, organizations can modernize their integration infrastructure, streamline operations, and scale seamlessly.
In this blog, we’ll take you through the what, why, and how of migrating from IB to IIS, enriched with architectural insights, real-world benefits, and a detailed step-by-step migration process. We’ll also explore how NeosAlpha’s specialized experience makes this transition not just possible, but optimal.
What Is Intapp Integration Builder?
Intapp Integration Builder (IB) is a legacy integration toolkit that allows firms to create custom connections between their business systems and Intapp’s suite of applications. Traditionally deployed on-premises, Integration Builder was designed during a time when cloud adoption was low, and IT teams had more direct control over their infrastructure.
It enabled organizations to set up scheduled data transfers, orchestrate workflows based on system events, and manipulate data flows through scripting. For many years, this served as a functional backbone for firms automating routine operations.
However, IB was built for a different era, before cloud-first strategies, agile development models, and real-time data exchange became business-critical needs.
Capabilities of Intapp Integration Builder
- Script-based integration logic
- Event triggers and time-based scheduling
- Integration with Intapp apps like Time, Conflicts, and Intake
- Basic transformation and data mapping
Limitations of Intapp Integration Builder
Despite its utility, Integration Builder comes with significant constraints today:
- Limited scalability under high-volume transactions
- No native cloud support or elasticity
- Requires extensive manual monitoring
- Rudimentary logging and error tracking
- Inadequate support for modern authentication protocols like OAuth
- On-prem deployment with limited cloud reach
What Is Intapp Integration Service?
Intapp Integration Service (IIS) is a cloud-native iPaaS (integration Platform-as-a-Service) built on Boomi, purpose-designed to support the dynamic integration needs of modern professional service firms. It combines the security and compliance focus of Intapp with the agility, scalability, and low-code flexibility of Boomi’s proven integration engine.
Unlike Integration Builder, which is tightly bound to on-premises deployments, Intapp Integration Service is designed for both cloud and hybrid environments. It supports real-time integrations, comes with a large library of prebuilt connectors, and offers robust monitoring and alerting features.
But the true value of IIS lies not just in technology, but in transforming how firms operate. With IIS, integration becomes a strategic capability rather than a reactive function.
Core Differences Between Intapp Integration Builder and Intapp Integration Service
Let’s break down some key architectural and functional differences:
| Feature | Intapp Integration Builder (IB) | Intapp Integration Service (IIS) |
| Deployment | On-premises virtual appliance | Cloud-native (Boomi-based) |
| Interface | Java client + web access | Browser-based Boomi UI |
| Integration Unit | Rule / Project | Process |
| Execution | Black box appliance | Boomi Atom or Molecule |
| Updates | Manual by IT admin | Automatic (cloud), manual (Atom) |
| Connectors | Custom HTTP/SQL/data sources | 1,500+ prebuilt Boomi connectors |
| Scheduling | Events engine | Atom-level scheduling |
| Auth support | Basic HTTP/headers | OAuth 2.0, API tokens |
Why Move to IIS?
The decision to migrate from IB to IIS is more than just a technical upgrade; it’s a strategic modernization initiative. Below, we unpack the key reasons firms are making this move:
1. Cloud-Readiness and Hybrid Flexibility
Modern firms increasingly operate in a hybrid environment where some applications are on-premises and others reside in the cloud. Intapp Integration Service (IIS)offers seamless support for both models through Boomi’s Atoms (for single-system execution) and Molecules (for clustered runtime environments). This flexibility is crucial for firms navigating digital transformation.
2. Improved Developer Productivity
IIS features a low-code drag-and-drop interface, reducing the need for custom scripts. Developers can build and modify integrations much faster, enabling IT teams to respond quickly to business changes. Templates and reusable components make onboarding new systems or workflows a breeze.
3. Enhanced Monitoring and Reliability
Unlike Integration Builder, which lacks deep visibility into workflow failures, IIS provides detailed dashboards, audit logs, and alerting mechanisms to enhance visibility. You can track success rates, debug failed jobs, and automate remediation, all within a centralized console.
4. Built-in Security and Compliance
IIS supports modern authentication standards such as OAuth 2.0 and integrates easily with Microsoft Azure Active Directory for Single Sign-On (SSO). It is also designed to meet SOC 2 and GDPR compliance standards, making it a safer choice for firms handling sensitive client data.
5. Scalable Performance
Thanks to Boomi’s underlying cloud infrastructure, IIS can handle high transaction volumes without slowing down. As your firm grows and data exchange increases, IIS scales automatically to match demand, something Integration Builder (IB) was never built for.
Understanding the Intapp Integration Service (IIS) Architecture
To appreciate the leap in capabilities, it helps to visualize how IIS is structured:
| Component | Description |
| Boomi Atom/Molecule | Execution environments that run workflows, either on-premises or in the cloud. |
| Integration Canvas | A low-code UI for designing integration processes using drag-and-drop tools. |
| Prebuilt Connectors | Over 1,500 connectors available for systems like NetSuite, Salesforce, iManage, SAP, etc. |
| Monitoring Dashboard | Tracks performance metrics, error logs, and SLA compliance in real time. |
| API Gateway | Allows exposure of internal APIs securely for external consumption. |
| Audit Logs & Security Controls | Tracks user activity and data flows for compliance reporting. |
Similarities Between Intapp Integration Builder and Intapp Integration Service
Despite their architectural differences, IB and IIS share many conceptual similarities:
- Data Movement: Both platforms enable you to move and transform data across endpoints.
- Workflow Structure: Both use shapes to define steps in a process.
- Variables & Parameters: Both support dynamic data manipulation using internal variables.
- Mapping & Functions: Both provide transformation tools to map source to target structures.
- Scheduling: Time- or event-based triggers can initiate processes in both.
The key advantage of IIS is how it modernizes these capabilities. For example, what used to be a Rule Input in IB becomes a Process Property in IIS, but with cleaner separation, reusability, and environment-specific overrides.
IIS as a Middleware: More Than Just Integration
What sets IIS apart is its potential to act as a middleware platform, a central hub where all system interactions converge. This has several benefits:
- Unified Data Governance: Ensure consistent data definitions and formats across systems.
- Faster Change Management: Update rules and logic in one place without touching multiple systems.
- Operational Resilience: Isolate failures and reroute data flows without interrupting business processes.
IIS simplifies the integration landscape from a chaotic mesh of point-to-point scripts to a well-governed, maintainable hub-and-spoke model.
A Step-by-Step Guide to Migrating from IB to Intapp IIS
Migration doesn’t have to be complex. Here’s how firms typically approach the journey:
Step 1: Inventory and Assessment
Document all current IB workflows, data sources, and destinations. Understand what each integration does, how often it runs, and which stakeholders it impacts.
Step 2: Prioritization
Classify integrations based on criticality and complexity. Start with low-complexity, high-value processes to gain early momentum.
Step 3: Design in IIS
Use the Boomi Process Canvas to recreate the logic. Leverage prebuilt connectors wherever possible. Introduce modern features like real-time triggers or OAuth authentication as enhancements.
Step 4: Development and Testing
Develop workflows in a test environment. Use Boomi’s testing tools to simulate scenarios, validate transformations, and catch edge cases.
Step 5: Deployment
Deploy workflows to production with CI/CD best practices. Start with non-critical processes and progressively migrate the rest.
Step 6: Decommission IB
Once confidence is high and performance is stable, retire the corresponding IB workflows. Archive scripts and logs for compliance.
