If you have 24+ months: Ideal time to start a strategic assessment and vendor selection.

If you have 12-18 months: Begin budgeting, system selection, and proof of concept (PoC).

If you have less than 12 months: Immediate action needed for risk mitigation and phased migration.

ERP vendors stop supporting older versions and push customers to modern ERP systems for several key reasons, often driven by technological advancements, security concerns, and business strategy. Here’s why vendors make this move:

Security and Compliance Risks

• Cybersecurity Threats: Older ERPs become vulnerable to modern cyber threats since they no longer receive security patches and updates.
• Regulatory Compliance: Businesses must comply with data privacy laws (e.g., GDPR, HIPAA, SOX), and outdated ERPs may not meet evolving legal requirements.

High Maintenance Costs for Vendors

• Supporting older ERP versions requires dedicated teams for bug fixes, compatibility testing, and customer support.
• As technology evolves, maintaining compatibility with newer operating systems, databases, and cloud environments becomes costly and inefficient.
• Vendors prefer to allocate resources toward innovation rather than maintaining outdated systems.

Push for Cloud and Subscription Models

• Many ERP vendors are shifting from on-premise licensing to cloud-based, subscription-based models (SaaS) for predictable revenue.
• Cloud ERPs provide vendors with continuous updates, eliminating version-based support challenges.
• Subscription models allow vendors to earn recurring revenue rather than one-time licensing fees.

Technological Advancements & Competitiveness

• New ERP versions come with AI-driven automation, analytics, IoT integrations, and machine learning, which are not feasible in legacy systems.
• Vendors want to stay competitive by offering modern features that enhance business intelligence, automation, and remote accessibility.

Drive Customer Lock-In and Standardization

• Forcing migrations allows vendors to standardize their offerings, reducing complexity in managing multiple ERP versions.
• Modern ERPs often limit heavy customizations, making future updates easier for vendors and keeping customers within their ecosystem.

End-of-Life (EOL) Strategy to Drive New Sales

• By discontinuing support, vendors encourage customers to purchase new ERP licenses, cloud subscriptions, or additional services.

This shift increases revenue opportunities for vendors in consulting, migration services, and integrations.

1. Evaluate alternative ERP solutions (not necessarily from the same vendor).
2. Negotiate extended support if migration is not immediately feasible.
3. Plan a phased migration rather than rushing into a system that may not fully meet business needs.
4. Consider third-party ERP support providers that specialize in maintaining older systems beyond vendor support timelines.

A no-code Integration Platform as a Service (iPaaS) can play a crucial role in migrating from a legacy ERP to a modern ERP by simplifying data movement, automating workflows, and ensuring seamless connectivity between old and new systems. Here’s how it can help:

Data Extraction, Transformation & Migration

• Extract data from the legacy ERP using pre-built connectors or APIs.
• Cleanse and transform data before loading it into the new ERP.
• Map legacy data fields to modern ERP formats without complex coding.
• Automate bulk data transfers to avoid manual errors.

Example:

A no-code iPaaS can pull customer records, invoices, and order history from an old on-prem ERP (e.g., SAP ECC) and automatically restructure it for a cloud ERP (e.g., SAP S/4HANA, NetSuite, or Microsoft Dynamics 365).

Bridging Old and New ERPs During Migration

• Many businesses run both systems in parallel before fully switching.
• A no-code iPaaS can sync real-time data between the old and new ERP, avoiding business disruptions.
• Ensures that changes in the old system (e.g., inventory updates, order processing) are reflected in the new ERP.

Example:

While migrating from Oracle E-Business Suite (on-prem) to Oracle Cloud ERP, an iPaaS ensures that financial transactions recorded in the old system sync automatically with the new ERP.

Integrating ERP with Existing Applications

• Modern ERPs require connections to CRMs, HR systems, e-commerce, and supply chain tools.
• A no-code iPaaS helps connect legacy ERP with third party apps (Salesforce, Shopify, Workday, etc.) and eliminate the brittle custom coded integrations that have been built over the past 20-30 years.   
• When it’s time to migrate to modern ERP it is then only a matter of turning off the legacy integration connection and plugging in pre-built modern ERP connectors.
• This approach front loads the hard integration and data automation work, and eliminates the need for custom API development, reducing costs and implementation time when a company finally kicks off the migration work.

Example:

A company migrating from Dynamics GP to Dynamics 365 Business Central can use an iPaaS to link Salesforce (CRM), Workday (HR), and legacy data sources in one unified workflow.

Automating Business Processes

• Automates repetitive tasks during migration (e.g., data validation, approvals, and error handling).
• Can create event-driven workflows, ensuring key processes are not disrupted.
• Ensures data consistency by applying business rules and logic across systems.

Example:

An iPaaS can automatically validate and flag duplicate customer records before they are imported into a modern ERP.

Enabling API-Less Connections for Non-API Legacy ERPs

• Some legacy ERPs lack modern API capabilities, making integration difficult.
• No-code iPaaS offers connectors, file-based transfers (CSV, XML, EDI), and orchestrated data flows to bridge the gap.
• Helps businesses integrate systems without needing custom API development.

Example:

An iPaaS can extract purchase orders from an AS400-based ERP using file-based triggers and sync them to a new ERP like Microsoft Dynamics 365.

Ensuring a Faster and Cost-Effective Migration

• Reduces IT dependency by allowing business users to handle integrations.
• Minimizes migration risks by providing pre-built templates for common ERP integrations.
• Shortens project timelines by eliminating manual coding and testing.

Example:

A manufacturer moving from JD Edwards (on-premise) to SAP Business ByDesign (cloud) can complete migration in months rather than years using an iPaaS.
