Deployment & migration

A poorly managed network migration can cost days of lost production. Preparation is everything.

The move date arrives. Keys to the new premises are available Friday. Monday morning, everyone needs to be working.

In practice, improvised network migrations translate into lost production days, inaccessible files and blocked teams.

ARCrezo manages your network infrastructure migration end to end — with a methodical preparation that turns a high-risk moment into a controlled transition.

Network infrastructure migration with zero downtime

Does this sound familiar?

●You are moving to new premises and need to transfer your entire network infrastructure

●You are merging two sites and need to harmonise the networks

●You are migrating to partially or fully hosted infrastructure (cloud, datacentre)

●You have experienced a chaotic migration in the past and want to avoid repeating it

Scope of work

✓Audit and inventory of the infrastructure to be migrated

✓Migration plan design (architecture, sequencing, rollback procedure)

✓Installation and configuration of the network at the target site

✓Progressive migration or cutover depending on continuity constraints

✓Validation tests at the new site before decommissioning the old one

✓Complete documentation of the new infrastructure

What is not included

✕Physical transportation of equipment — ARCrezo coordinates but does not move boxes

✕Data or application server migration — unless explicitly included in scope

Deliverables

✓Detailed migration plan with milestones and rollback procedure

✓Operational network at the target site

✓Updated documentation of the new architecture

✓Signed technical acceptance report

✓Post-migration support during stabilisation

How it works

Inventory

Map the existing infrastructure, identify dependencies and migration risks.

Design

Define the target architecture, migration plan, sequence and rollback procedure.

Execute

Deploy at the target site, test, cut over according to the validated plan.

Stabilise

Monitor the first few days, handle adjustments, close with final documentation.

Why ARCrezo?

✓Risk anticipation: the rollback procedure is defined before the start, not after an incident

✓Service continuity: our objective is zero unplanned production hours lost

✓Systematic documentation: the new infrastructure is documented from the moment of deployment

Frequently asked questions

Can we migrate without interrupting production?

In most cases, yes — with proper preparation. Some phases require a short planned outage outside business hours.

How much time is needed to plan a migration?

Planning typically represents half the project. For a medium-sized site, allow 2 to 4 weeks of preparation.

What happens if something does not work after cutover?

The rollback procedure is defined before execution. ARCrezo provides post-migration support during the stabilisation period.
