VLAN and network migration services
Gateflow plans and implements network migrations so existing services can move to the agreed network structure. The work covers VLAN assignments, switch and host configuration, and checks from the applications that depend on those connections. Your team receives an agreed migration sequence and a record of the resulting configuration, including any connections that still need attention.
Network migration planning
Gateflow reviews the current network plan against available device configurations and the changes you need. The assessment identifies affected systems, administrative access and dependencies on external operators. IT infrastructure support provides the wider operating context. Before implementation, the proposal names the equipment and software versions covered, the tasks Gateflow will perform and decisions that remain with your network owner.
VLAN mapping
The migration needs a usable mapping between current and target VLANs. Gateflow records subnet assignments, gateways and the systems connected to each segment. Shared services and management connections receive explicit entries because their users may span several networks. Conflicting addresses or undocumented assignments become decisions for the preparation phase, before a device changes its network connection.
Switch port configuration
Gateflow checks which ports carry a single VLAN and which carry tagged traffic for several segments. The change plan connects each approved port configuration to the attached device and the intended path upstream. Physical installation and cable moves are separate work packages. Data center installation and moves can cover those tasks when the network migration also requires work in the rack.
Routing and access rules
A working link does not establish that an application has the connections required for normal use. Gateflow reviews the agreed routes and permitted traffic with the people responsible for routing and firewalls. The resulting test list names source and destination systems and the relevant service. Changes to access rules require approval from the customer responsible for those rules.
Network migration cutover
Gateflow divides the change into groups of systems that can be moved and checked together. Each step has a named operator, an approval point and a condition for stopping or returning to the previous configuration. The project process also records how remote administrators retain access during the change. Your team agrees the maintenance window before production settings are modified.
Network connection testing
Testing follows the agreed paths from client or application to destination, including name resolution where required. Gateflow records the checks performed after each migration group and investigates differences from the expected result. Application owners confirm their own service behavior. An unresolved test stays visible in the change record, with an owner and a decision about further rollout.
Network configuration handover
Gateflow updates the VLAN and port records to match the accepted configuration. Your operating team receives the relevant configuration files, test results and remaining work in the agreed repository. The handover also identifies settings restored during a failed step. Follow-up maintenance or additional migration groups can be commissioned against this documented state without reconstructing the previous change.
Network migration project support
Gateflow is based in Frankfurt and scopes network projects across Germany. Remote preparation and on-site attendance depend on device access and the work involved. Information about Gateflow describes the company's infrastructure and software services. For an initial discussion, provide the network overview, equipment versions and intended migration date; recruiters can send the defined project responsibilities and attendance requirements.
Plan your network migration
Gateflow implements the agreed VLAN and network changes and checks the required connections. You will receive the updated configuration, port mapping and test records for ongoing operation.
