When switching to a new ERP system, your existing data goes through a structured migration process: extraction, transformation, and loading into the new platform. The process includes data mapping, validation, and testing phases to protect data integrity. At Opus Flow, we handle this through dedicated migration teams and automated tools — making the transition secure and systematic for sustainable installation companies of all sizes.

What exactly happens to your data when you switch ERP systems?

Your business data goes through a three-phase migration process when switching ERP systems. Each phase is distinct, and understanding them helps set realistic expectations before you begin.

Phase 1: Extraction

The extraction phase involves pulling all relevant data from your current system — customer information, project records, financial data, inventory details, and historical transactions. Nothing is deleted or moved until a secure copy exists.

Phase 2: Transformation

During transformation, data mapping takes place: fields from your old system are matched to corresponding fields in the new ERP. This phase also includes data cleansing — removing duplicates, correcting formatting inconsistencies, and validating accuracy. For sustainable installation companies, this typically covers customer databases, project portfolios, equipment specifications, supplier information, and service histories.

Phase 3: Loading

The loading phase imports the transformed data into your new ERP in controlled batches. We use automated migration tools and dedicated product experts to ensure a smooth transfer. Multiple validation checkpoints verify data integrity and completeness before you go live.

How do you ensure your business data stays secure during ERP migration?

Data security during ERP migration depends on enterprise-grade encryption and secure transfer methods applied throughout the entire process — not just at the point of transfer.

Before any migration activity starts, we create encrypted backups of your existing data. During the transfer itself, data moves through secure channels using industry-standard encryption protocols. Access is restricted to authorised personnel only, with detailed activity logs maintained for compliance purposes.

Opus Flow operates under enterprise contracts with technical infrastructure partners, ensuring all migration activity occurs on secure, monitored networks. We provide security documentation and compliance certifications on request. Each migration phase includes integrity verification steps, and rollback capabilities are in place if any issue arises.

What are the biggest risks of losing data when changing ERP systems?

The most common causes of data loss during an ERP transition fall into a few distinct categories:

• Incomplete data mapping — fields from the old system don’t have a corresponding home in the new one
• Format incompatibility — data structures that don’t translate cleanly between platforms
• Inadequate backup procedures — no recovery path if something goes wrong
• Human error — manual handling introduces mistakes that automated tools avoid
• Insufficient testing — issues that would have surfaced in a test run appear after go-live instead

For sustainable installation businesses, custom fields, specialised workflows, and industry-specific data structures are particularly vulnerable. Historical project data, third-party integrations, and automated workflow configurations require careful mapping — they rarely transfer correctly without dedicated attention.

The most effective mitigation approach combines a thorough data audit before migration, multiple backup copies, and a phased migration strategy. We use automated tools and dedicated consultants to reduce manual handling. Running both systems in parallel during the final validation stage allows you to confirm data accuracy before fully switching over.

How long does it take to transfer all your data to a new ERP system?

Data migration typically takes 2–8 weeks, depending on data volume, system complexity, and the number of integrations involved.

The main factors that extend timelines include:

• Large volumes of historical data
• Multiple locations or business units
• Complex inventory management or project structures
• Custom field mapping and workflow recreation
• Third-party system integrations requiring reconnection

Simple installations with straightforward data structures can complete migration in 2–3 weeks. Larger businesses with extensive histories and custom integrations typically need 6–8 weeks or more.

Our onboarding process is built around this reality. We assign dedicated product experts who manage migration timelines end-to-end — covering data migration, automation setup, customisations, and staff training. Tailored configuration, hands-on consultant support, and interactive test environments mean your team can explore the new system risk-free before going live. The result is a shorter learning curve and a faster return on investment.

Successful ERP data migration requires careful planning, professional expertise, and thorough testing. We provide dedicated migration support, automated tools, and robust security measures to ensure your data transfers safely and completely. Investing in a structured migration process protects your business information and sets the foundation for stronger operational performance in your new system.
