Baan to Infor LN Migration Readiness Assessment
This free assessment scores how ready your organization is to migrate from Baan IV or Baan V to Infor LN, built for IT directors, ERP managers, and CFOs at discrete manufacturers still running legacy Baan. Answer ten questions about your data, customizations, people, integrations, and governance, and you get an instant readiness score with a band-specific action plan. Most Baan migration failures trace back to gaps that were visible before the project started - this tool makes those gaps explicit so you can fix them before they become change orders.
1. Which Baan version are you running today?
2. How well is your customization portfolio documented?
Include custom 4GL sessions, modified standard sessions, custom tables, and Exchange schemes.
3. What is the state of your master data (items, BOMs, routings, business partners)?
4. Do you have executive sponsorship and an approved budget range?
5. How deep is your in-house Baan and Infor 4GL expertise?
Migration projects lean heavily on people who understand your current Baan configuration and Tools customizations.
6. Is your integration landscape documented (EDI, shop floor, PLM, custom interfaces)?
7. How standardized are business processes across your sites and business units?
8. What testing capability do you have for a major ERP change?
9. Have you decided on the target deployment model for Infor LN?
10. How prepared is the organization for change management and training?
How the readiness score works
The assessment covers the ten dimensions that most reliably predict Baan-to-LN migration outcomes, based on patterns across dozens of legacy Infor migrations in aerospace, defense, and discrete manufacturing. Each question is scored 0-3, and your total is expressed as a percentage of the maximum. The dimensions are deliberately weighted toward the factors that create budget overruns in practice: undocumented customizations, unprofiled master data, and missing executive sponsorship. A single low-scoring dimension rarely kills a project, but two or three combined is where 40-60% cost overruns come from. Treat your lowest scores as your critical path, not your average.
Why Baan migrations fail differently than other ERP projects
Baan IV and Baan V environments have typically been running for 20-30 years, which creates failure modes newer ERP replacements do not face. The people who built your customizations are often retired. Baan 4GL customizations do not port directly to LN, so every custom session is a rebuild-or-retire decision. And decades of accumulated data means migration effort is dominated by cleansing, not loading. The most common pattern we see:
- Customization counts underestimated by 2-3x because unused sessions were never inventoried
- Master data cleanup consuming 30-40% of total migration effort
- Key-person risk surfacing mid-project when the one remaining Baan expert becomes a bottleneck
- Site-level process variants breaking the global template during rollout
How to interpret your result
A score below 40% means preparation should come before partner selection - starting a migration from this position typically adds 6-12 months and significant cost through mid-project discovery. Scores of 40-69% mean you can begin planning in parallel with targeted remediation, but your two weakest dimensions should be fixed before contracts are signed. Above 70%, your risk profile supports moving into detailed planning, licensing negotiation, and partner selection. In every band, the score is a conversation starter with your executive team: it converts a vague sense of technical debt into specific, fundable workstreams with clear owners.
How Netray helps you act on your score
Netray specializes in legacy Infor and Baan environments - we combine deep Baan 4GL and Infor LN expertise with AI-assisted analysis tooling that inventories customizations, profiles data quality, and maps integration landscapes in weeks instead of months. If your score exposed gaps, we run focused readiness sprints: customization rationalization, data profiling, and migration roadmapping. If you scored migration-ready, we provide independent estimates, phased migration planning, and hands-on delivery. Either way, you get an engineering-led view of the work, not a sales-led one.
Frequently Asked Questions
How long does a Baan IV to Infor LN migration typically take?
For a single-site discrete manufacturer with moderate customization, plan on 12-18 months from contract to go-live. Multi-site environments with heavy Baan Tools customization commonly run 18-36 months when rollout waves are included. Readiness is the biggest lever: organizations that enter with documented customizations, profiled data, and a decided deployment model routinely cut 3-6 months off the timeline compared to those doing discovery mid-project.
Can Baan 4GL customizations be migrated directly to Infor LN?
Not directly. Baan Tools customizations must be rebuilt for LN, ideally using LN Studio and extension points rather than modifying standard objects. In practice 30-50% of legacy customizations are retired because standard LN now covers the requirement or the function is no longer used. That is why a customization inventory with usage data is the single highest-value preparation step - it turns an unknown rebuild bill into a scoped decision list.
Is staying on Baan IV a viable option instead of migrating?
It can be a deliberate short-term position, but it is not free. Mainstream support has ended, the talent pool shrinks every year, and security and compliance exposure grows - especially for defense and aerospace suppliers facing CMMC and export-control audits on unsupported platforms. Use our Baan IV End-of-Life Risk Cost Calculator to quantify what staying actually costs per year, then compare that against a phased migration investment.
