What a colocation migration involves
A colocation migration moves your equipment, and the connectivity it depends on, between facilities. It includes cabinet and space readiness at the destination, power and cooling confirmation, circuit and cross-connect provisioning, the physical move, and the network cutover that makes the new site live.
Consolidations, provider changes, lease endings and capacity moves all follow the same pattern, with different timing pressure.
Mapping circuits, IP ranges, VLANs and peering
We help map what the move depends on: circuits and carriers, IP ranges, VLANs, peering relationships and firewall rules. That map becomes a cutover runbook with a maintenance window, validation steps and a rollback path.
Circuit lead times are usually the longest item on the schedule, so we flag them early and set the physical move date only once the destination connectivity is confirmed.
- Circuit, carrier and cross-connect lead times tracked from day one
- IP, VLAN and peering mapping before any equipment moves
- A parallel-run window where the design allows it
- Connectivity validated at each stage before the old path is retired
The physical move, planned around the cutover
Equipment is inventoried, labeled, packed and moved on air-ride trucks with a chain of custody, then re-racked and re-cabled to the documented design. Delivery is timed to the cutover window so equipment is not sitting on a dock while a maintenance window expires.
Phased moves and parallel running
Where downtime must be minimal, the migration can run in waves, with old and new sites live together while services are cut over in sequence. Each wave has its own acceptance criteria, so a problem in one wave does not stall the rest.
What to have ready before we start
These items let us build the plan quickly.
- The colocation contract dates, including any exit deadline
- Equipment list and current cabinet layout
- Carrier and circuit details for both sites
- Network diagrams, IP ranges and VLAN lists
- Your maintenance windows and approval contacts
