Physical migration and virtual consolidation are different problems, needing different solutions, tackled in sequence. Most transformation frameworks assume the physical estate is already resolved. For many organisations, it isn’t.
Phase 1: Physical transition
- Decant. Consolidate. Stabilise.
The first phase focuses on the physical estate: ageing on-premise server rooms, legacy data halls, distributed branch infrastructure, or a mix of all three. That physical complexity has to be addressed before any meaningful cloud or hybrid strategy can take shape.
Datum acts as a neutral landing zone during this phase. Instead of forcing an immediate decision about where every workload will ultimately live, organisations move infrastructure into Datum’s carrier-neutral colocation environment first. This separates the urgency of physical relocation from the complexity of long-term design decisions. IT teams get room to assess, audit and prioritise without committing to a permanent footprint.
During Phase 1, Datum provides flexible rack space and power with short-term access options. No organisation should be locked into a configuration that stops matching where they expect to be in 18 months. Physical security, resilience and compliance requirements are in place from day one, taking pressure off the teams managing the decant. What’s left is a stable, auditable base Phase 2 can be planned against with confidence.
Phase 2: Virtual consolidation
Once the infrastructure is consolidated and stable, Phase 2 is where the hybrid IT strategy takes shape. Questions too risky to answer during a live migration, including which workloads move to public cloud, which stay in colocation and which need dedicated connectivity, can now be worked through in sequence against a clear inventory.
Datum’s carrier-neutral connectivity is central to this phase. Datum facilities provide direct access to multiple cloud platforms and carriers, so organisations can build their target hybrid architecture without the lead times and costs of starting from a standalone environment. The connectivity is already there. The focus shifts from procurement to configuration.
As Phase 2 progresses, the colocation footprint often shrinks as workloads move to cloud or get retired altogether. Contracts are structured to accommodate that, letting the colocation environment evolve from a landing zone into a core hybrid anchor: the stable, connected point around which cloud and on-premise resources are balanced for the long term.
Together, the two phases give you a practical structure for sequencing decisions, allocating budget and setting realistic milestones, whether you’re building an internal business case or scoping a programme with a delivery partner.
