IT infrastructure migration: modernizing and securing your environments

Each project begins with a complete analysis of the existing environment: servers, VMs, storage, networks, security and application dependencies. We identify critical components, current performance, operating costs and weak points. This phase enables us to design an adapted, more robust and more efficient target architecture. Our audits also include compliance with security best practices, regulatory constraints and high-availability objectives.

We orchestrate the migration of servers to more modern environments, whether physical, virtualized (VMware, Hyper-V, Proxmox) or hosted in the Cloud. Images, configurations and data are transferred with a controlled approach, limiting interruptions. We also consolidate servers to reduce technological debt, improve resilience and rationalize costs.

Modern infrastructures rely on reliable, secure interconnections. We manage the migration and redesign of local area networks (LANs), wide area networks (WANs) and Wi-Fi, integrating security right from the design stage. This expertise includes network segmentation, SD-WAN implementation, next-generation firewall configuration and real-time monitoring to ensure optimal connectivity after the switchover.

During a merger, acquisition or reorganization, it becomes necessary to migrate a Microsoft 365 or Azure tenant. IT Systèmes handles the complete transfer of users, licenses, mailboxes, OneDrive files, SharePoint sites, Teams groups and associated Azure resources. This sensitive migration is carried out seamlessly, with continuous synchronization and respect for permissions. Our tools and methods guarantee a smooth migration, with no loss of data or service interruptions, even in large environments.
