Solution I - Data Readiness Assessment
for ERP Migration

Why Data Readiness Matters

The success or failure of an ERP implementation is heavily dependent on the quality and readiness of your data. Too often, organizations treat data cleansing as a generic, isolated activity-leading to misaligned data, delays in cutover, and costly post-go-live fixes.

Our Data Readiness Assessment is a purpose-built offering designed to evaluate the health, structure, and alignment of your existing data against the specific data models and business rules of your target ERP system-whether SAP, Epicor, Oracle, or another platform.

This assessment forms the critical foundational phase of our comprehensive Data Migration offering, this service equips you with the strategic foresight and technical precision needed for a successful ERP rollout. It transforms uncertainty into action by defining the scope, sequencing, and resource requirements for data migration—allowing you to seamlessly integrate these into your broader ERP implementation roadmap

Case 1 - Assessment for Epicor ERP Migration

You’ve made the decision to move your business forward with Epicor – but now comes the real question: what do you do with your legacy data?

At this stage, many companies face uncertainty around what data is truly required for Epicor, what condition it’s in, and how much cleansing is actually needed. That’s where IndexCo Data comes in.

We help you gain practical, clear-eyed insight into your current data landscape – identifying key domains, assessing data quality, pinpointing critical gaps, and mapping everything to what Epicor actually expects. Our approach is business-led and lean: we help you avoid the trap of over-cleansing or over-engineering your data, which only leads to wasted time and resources.

Instead, our Data Readiness Assessment focuses on the data that matters most – so you can migrate with confidence, knowing what to fix, what to keep, and what to ignore.
