Data Prep Done Right: How Hopp Tech Helps You Clean & Prepare for Migration

When you think about data migration, the glamorous moment often comes at go-live.

But the foundation for success is laid in how you clean, model, and validate your data.

At Hopp Tech, we believe this phase is a strategic advantage.

Why Data Prep is Your Secret Weapon

Bad data is the silent killer of migrations.

If you move low-quality, inconsistent, or incomplete information, every downstream step becomes riskier, your test cycles slow down, issues pile up, and confidence erodes just when you need it most.

Hopp solves this by integrating data quality and business logic directly into the migration framework.

Unlike traditional ETL-style migrations, which treat data as rows and tables, Hopp models your migration around business objects, logical units like "Customer," "Product," or "Account" that make sense to your business.

This means you move meaningful records, in context, with their rules and dependencies intact.

The Hopp Data Prep Journey

Here's how data preparation with Hopp typically plays out, refined, iterative, and built for collaboration:

1. Profiling & Discovery

You start by analyzing your source systems to understand what you actually have. What are the data structures? Which fields are missing or malformed?

This early profiling kick-starts the process with clarity.

2. Defining Business Objects

Instead of breaking things down into technical tables, you define business objects in Hopp Studio.

This aligns the migration scope with how your company, or your business users, thinks about its data.

3. Mapping & Validation Rules

In Studio, you build two separate maps:

• A Target Map which reflects what the target system expects.
• A Source Map which represents your legacy data.

These are linked through a clean interface, and you layer on validation rules, transformations, and business logic.

4. Unit-by-Unit Migration (Batches)

Hopp uses a unit-of-migration approach, meaning each "business object" is treated as a consistent, atomic unit during migration.

That helps you avoid partial, inconsistent data and gives you flexibility to rollback if something goes wrong.

5. Iterative Execution & Testing

You don't do a one-and-done.

With Hopp's Core component, you generate the migration code and execute in iterations. Each run, you validate, identify issues, fix them, and re-run.

This reduces risk and lets you refine data before the final cutover.

6. Collaboration & Monitoring via Portal

Hopp's Portal is your single pane of glass for tracking progress.

You can:

• Initiate migration jobs
• Monitor events and issues in real time
• Assign tasks and responsibilities
• Drill down into specific business objects for root-cause analysis

This means business teams and IT are aligned; everyone can see the status, comment, and make decisions based on the same data.

7. Validation & Reconciliation

After each iteration, you validate using built-in rules and reconciliation logic. Hopp also supports auditing so you can track what changed, why, and when.

8. Cutover & Post-Migration Monitoring

Once you're confident in the data, you can execute your final load.

After migration, you continue monitoring, cleaning, and optimizing, ensuring your new system starts with high-quality data and stays clean.

Why Hopp's Approach Beats Traditional Migration Tools

• Business-Centric Units: Instead of piecemeal table migration, Hopp migrates business objects. That keeps data coherent, traceable, and meaningful.
• Separation of Concerns: By maintaining separate source and target maps, you get a clear, reusable structure that's not buried in custom ETL code.
• Automation + Low Coding: The Core generates migration code automatically, reducing manual coding and minimizing risk.
• Scalable & Transparent Execution: With a Portal for orchestration, you manage jobs, events, audits, and team collaboration in a unified interface.
• Agile & Iterative: You can run many cycles. Clean, validate, fix, repeat, which drastically reduces surprises at cutover.

Bottom Line

Data prep isn't just a "nice to have", done the right way, it's the backbone of a smooth, reliable migration.

With Hopp Tech, you treat data as real business entities. You clean and validate in context. You catch errors early. And you do it all in a transparent, repeatable way.

If you want your migration to succeed investing in data prep through Hopp is the smartest move.
