Industrial Network Migration

Average response is not a resolution time or a contractual guarantee. Support scope and response commitments are agreed for each engagement.
Industrial network migration changes links that live equipment may depend on. Addresses, multicast traffic, timing and startup order all need care. We plan the move in stages with the site’s operational owners. Each stage has checks and a recovery route, so the old equipment is not removed before those decisions are clear.
Cisco-focused engineering
Design around the platform, traffic and failure behaviour you actually operate.
Change with evidence
Use pre-checks, acceptance criteria and a documented route back.
Operational handover
Keep the configuration, diagrams and responsibilities understandable after delivery.
Establish what is actually being replaced
The scope may involve access switches, a routed backbone, management systems or the boundary between operational and business networks. We find the interfaces, devices and apps affected by each part of the change. An equipment list alone does not show the consequences of moving a cable from one port to another.
We collect current settings, port records, addressing information and supplier constraints. Where records are incomplete, the plan includes an authorised discovery activity rather than treating assumptions as facts. Unknown connections should be investigated or clearly held outside the cutover, not moved simply because they appear on the same old switch.

Check compatibility beyond Ethernet link status
Legacy equipment may use unusual negotiation settings, fixed addresses, specific multicast behaviour or protocols sensitive to network changes. We review the supported features of the replacement Cisco platform and the needs of connected systems. A link coming up proves only part of the service.
The migration may also expose differences in security defaults, spanning-tree behaviour or management access. We compare the intended setup with the old live state and identify which differences are deliberate improvements. Copying every historical setting can preserve faults, but removing unexplained settings without investigation can break a legitimate dependency.
A useful starting point
Not sure where to start?
Bring the requirement. We will help you define the engineering work.
Agree supplier and operational responsibilities
Control-system vendors may need to confirm support, adjust an endpoint or attend acceptance testing. We identify those tasks early and arrange the right contacts for the maintenance window. A network engineer should not be expected to approve a process restart or change an app that belongs to another supplier.
The customer also needs an operational owner who can confirm whether production is in a safe state for the change. The project plan records who may stop the migration, who can authorise recovery and who decides that the process is ready to resume. Those are practical duties, not merely names on a contact list.
Different environments. The same care.

Finance, banking and the wider private sector. We start with the systems and people that depend on your connections.

Data centre networks ↗Stage equipment and rehearse the sequence
Preconfiguration can reduce time spent making decisions at site. We check software, management access, port assignments, optics and supported features before rollout. Where representative equipment or a test setup is available, we exercise the connections and behaviour in uses most likely to be affected.
The cutover sequence accounts for dependencies between switches and endpoints. Moving an upstream gateway too early can isolate equipment needed to check later steps. We prepare labelled cable and port schedules, records of the settings and a checkpoint after each meaningful stage. So the team can tell whether to continue or stop.
Make rollback physically possible
A recovery plan needs more than a copy of the old setup. We consider whether the original equipment remains available, how cables will be returned, whether addresses or endpoint settings have changed and how long restoration will take. Irreversible changes should be identified before the maintenance window is approved.
We also decide how long the old equipment remains protected from disposal or reuse. A spare switch that has already been repurposed is not a reliable rollback option. If the migration changes a broader architecture, recovery may require a different approach from simply reconnecting the previous hardware.
Validate the service with its owner
Post-change tests include network state and the operational workflows agreed with the customer. That may involve device communications, data collection, operator visibility, supplier access and controlled failover. Tests should cover any intended segmentation changes without introducing unapproved probing of sensitive devices.
We compare results with the pre-change baseline and record remaining issues. A plant returning to operation is an important milestone. But it does not on its own prove that every backup path or infrequent maintenance function works. The acceptance record distinguishes completed tests from deferred checks with named owners.
Stabilise and document the new environment
The transition period includes monitoring for link errors, unexpected traffic, device disconnections and configuration drift. We set out when the migration is considered stable and which problems remain within the project scope. Temporary access and migration-specific rules should be removed through controlled changes once they are no longer needed.
MCI can deliver an industrial migration from assessment through handover, or support your team during a defined cutover. The final records connect the new topology, settings and recovery procedures to the actual operational estate, providing a stronger starting point for future resilience reviews and maintenance.
