IT Migration for Networks and IT Security:
Switching Over Without Long Outages

Network, security and site migrations with clearly defined dependencies, coordinated maintenance windows and reliable rollback options.

Migration of network and security systems
About this service

Change with clear control

IT migration means moving network and security systems to new hardware, a different vendor, a new version or a new site without long downtime. It covers the inventory, a migration plan, the cutover in a maintenance window and a tested way back.

Planned across vendors and aligned with availability, security and ongoing operations.

Typical scenarios

When modernisation becomes necessary

Ageing platforms, increasing requirements and planned changes show when existing IT structures are reaching their limits.

End of life or end of support

Vendor support, security updates or replacement parts are being discontinued, increasing operational and security risks.

Performance or security limitations

Existing systems are reaching their capacity limits or can no longer meet current security requirements reliably.

Site relocation or expansion

Office moves, new locations or additional capacity change the requirements for network infrastructure, availability and connectivity.

The existing architecture no longer fits

New cloud, security or operating models can only be implemented to a limited extent with the current architecture.

High operational effort from legacy systems

Historically grown systems, manual processes and inconsistent configurations increase operational effort and the risk of errors.

Fragmented system landscape

Multiple platforms, vendors and operating models increase complexity and make consistent, maintainable operations more difficult.

SCOPE OF SERVICES

What we modernise

We modernise existing network and security environments through a structured, vendor-independent approach with clearly planned transitions into ongoing operations.

Switching and routing modernisation

Renew and consolidate access, distribution and core infrastructure, including VLANs, routing, uplinks and redundancy.

What you can commission from us

Fixed packages with a clearly defined scope. You receive the fixed price after a short assessment of your environment.

A changeover is coming up, but dependencies and risks are unclear.

  • Record current state and dependencies
  • Migration plan with approval points
  • Cutover and rollback plan
  • Fixed price for the implementation

You are switching vendors across several systems.

  • Translate configurations and rule bases
  • Match features before the switch
  • Test the new environment
  • Cutover with a tested way back

Your office is moving or a new site is being added.

  • Plan network and lines at the new site
  • Coordination with your providers
  • Move and commission the equipment
  • Support on the first working day

FREQUENTLY ASKED QUESTIONS

Questions about IT migration

What does an IT migration cost?

The effort depends mainly on the number of systems and sites, whether the vendor changes, the size of configurations and rule bases, cutovers outside business hours and the state of the existing documentation. After a short assessment you receive a fixed price for the chosen package.

How long will operations be down during the cutover?

That depends on the scope and is agreed in advance. We plan cutovers in agreed maintenance windows, with test points and a tested way back, so that downtime stays as short as possible.

What happens if something goes wrong during the cutover?

Every cutover has abort criteria defined in advance and a tested rollback plan. If a problem occurs, we return to the previous state in a controlled way.

Can you transfer configurations between vendors?

Yes. We translate rule bases, NAT, VPN and VLANs and match the features before the switch instead of converting them unchecked. We work across vendors, including Cisco, Fortinet, Sophos, Palo Alto Networks and HPE Aruba.

How does IT migration differ from a firewall or switch replacement?

If you only need to replace a firewall or your switches, you will find suitable packages under IT security and network infrastructure. IT migration covers changeovers that affect several systems, vendors or sites.
