🌱 IT SYSTEMES is committed to CSR!

Data migration is a critical process for any company wishing to modernize its information system, adopt a new business tool or switch to a Cloud infrastructure. It involves transferring all your information (databases, files, business histories, application content) to a new environment, while guaranteeing its integrity, security and availability. At IT Systèmes, we carry out secure, planned data migrations adapted to the technical and regulatory constraints of each organization. Our role is to ensure a smooth, loss-free transfer, whether it's a migration between SQL databases, a switch to a new application (CRM, ERP, accounting tool), or a complete transformation of your storage environment.

Our expertise in data migration

Audit and mapping of existing data

We analyze all your data sources (relational databases, files, business applications, messaging, etc.) to identify volumes, dependencies and information quality. This detailed mapping enables us to prioritize critical data and define an appropriate transfer strategy. We also highlight any redundancies and inconsistencies to prepare a cleaner, more optimized environment.

Migration between databases and heterogeneous systems

Switching from SQL Server to MySQL, from Oracle to PostgreSQL or from local storage to a Cloud cluster requires specialized expertise. Our teams are experts in conversion protocols and tools to guarantee total compatibility. We also manage the recovery of schemas, indexes and relationships to preserve the performance and reliability of your systems. This approach ensures a seamless transition and a fully operational environment right from the start of production.

Business data transfer (CRM, ERP, financial tools, EDM)

When changing business tools, data migration is often the most sensitive point. We ensure that your historical data, transactions, documents and specific parameters are correctly integrated into the new solution. We also carry out business consistency tests to ensure that the transferred data can be used immediately by your teams. This expertise guarantees functional continuity and productivity gains right from the start.

Security and regulatory compliance

Each migration is carried out in compliance with current regulations (RGPD, industry standards, ISO 27001). We implement encryption, authentication and traceability mechanisms to protect your sensitive data. Systematic backups and recovery plans are integrated to avoid any risk of loss. So you benefit from a secure, legally compliant migration.
