Daniel Smith, CEO at Astralis Technology, explains why decommissioning should be planned from the outset if organisations are to protect data, preserve asset value and meet sustainability goals.

The data centre conversation is understandably dominated by what comes next.

AI infrastructure, higher-density compute, cloud migration and modernisation programmes are changing what organisations need from their technology estates. Yet every transformation programme has another side to it: as new technology enters the data centre, existing infrastructure has to go somewhere.

That part of the transformation often receives less attention.

Decommissioning can still be treated as something to address once migration is complete: workloads have moved, new infrastructure is operational and attention finally turns to removing hardware that is no longer required.

As infrastructure requirements evolve at increasing speed, that approach can create unnecessary risk. Servers, storage and network equipment leaving an operational environment may still contain sensitive data, remain recorded on asset registers, carry residual value and contribute to environmental and sustainability reporting obligations.

Decommissioning should therefore be considered as part of a transformation programme from the beginning, rather than added at the end.

AI is changing the scale of the challenge

The growth of AI makes this increasingly important.

The International Energy Agency projects electricity consumption from accelerated servers, mainly driven by AI adoption, to grow by 30% annually to 2030 in its Base Case. Behind that growth sits a significant physical transformation of data centre infrastructure.

AI deployment can mean changes not simply to compute, but to storage, networking, power and cooling, creating cascading changes across existing estates.

Crucially, displaced equipment may not have reached the end of its useful life. A server that no longer meets the performance requirements of a particular workload could still have operational or commercial value elsewhere.

Infrastructure teams therefore increasingly need to manage two technology streams simultaneously: what is entering the environment and what is leaving it.

Planning only for the first can leave the second unnecessarily exposed.

Asset accountability cannot begin at the loading bay

One of the fundamental questions in a decommissioning programme is deceptively simple: what is being removed?

In a complex data centre environment, the answer may not perfectly match the asset register. Equipment moves, components are replaced, storage devices are swapped between systems and infrastructure evolves over many years.

Discovering discrepancies as equipment is being removed can create additional complexity.

Asset reconciliation should form part of transformation planning. Teams need to establish what equipment exists, where it is located, which assets contain data, who is responsible for them and their intended outcome.

That creates a baseline against which assets can remain accountable throughout decommissioning.

Switching off a server does not switch off responsibility for its data

Removing equipment from production does not remove the data it contains or the organisation’s responsibility for protecting it.

Storage media may retain corporate, customer, employee or other sensitive information long after a system has ceased providing a service. That makes chain of custody fundamental.

From the point an asset leaves its operational environment, organisations should be able to demonstrate who authorised its removal, who handled it, where it went and what happened to the equipment and any data-bearing media.

The appropriate method of data sanitisation or destruction should be determined before assets begin moving.

Secure decommissioning does not automatically mean physically destroying every data-bearing device. Where appropriate, verified data erasure can allow equipment to be reused while maintaining data security. Where erasure cannot be successfully completed, or where policy, risk or regulatory requirements dictate otherwise, physical destruction may be necessary.

The decision should be risk-based, controlled and documented rather than made simply because destruction appears to be the easiest option at the end of a project.

Compliance extends beyond the operational life of the hardware

Data protection, information security, environmental obligations, internal asset controls and audit requirements do not disappear when equipment is powered down.

For UK and European organisations, the ability to demonstrate what happened to data-bearing equipment can be as important as the process itself.

Evidence requirements should be defined early, including asset records, chain-of-custody information, records of data erasure or destruction and the eventual disposition of equipment.

Planning those requirements before migration begins can make it considerably easier to create a clear audit trail afterwards.

Retirement does not necessarily mean waste

Accelerated infrastructure change also creates a lifecycle question.

The European Commission reports that waste electrical and electronic equipment is increasing rapidly across the EU. Modern electronics contain valuable resources, including critical raw materials that can be recycled and reused.

But equipment leaving a data centre should not automatically be regarded as waste.

Some assets may be suitable for internal redeployment. Others may have a viable secondary-market life. Components may be suitable for reuse, while equipment that cannot be reused should enter appropriate recycling routes.

The distinction matters environmentally and financially. If decisions about reuse are delayed until equipment has already been removed, poor handling, incomplete asset information or unnecessary physical destruction can reduce its potential for a second life.

Disposition planning should consider the hierarchy of outcomes before the project begins: reuse where appropriate, redeploy where practical, preserve residual value where possible and responsibly process what cannot remain in use.

Reporting requirements should also be agreed early. Organisations may need to demonstrate not simply that assets were removed securely, but how equipment was reused, redeployed, resold, recycled or destroyed.

Five questions every transformation plan should answer

Every significant transformation programme should consider decommissioning from the outset.

Before migration or implementation begins, infrastructure teams should be able to answer five questions:

1. What infrastructure will the programme displace? Establish the asset baseline and reconcile records against the physical environment.
2. What data resides on it? Identify data-bearing equipment and agree the security, sanitisation and destruction requirements that will apply.
3. How will every asset remain accountable? Define responsibilities, chain-of-custody controls and the evidence required throughout removal.
4. What can have a second life? Determine the criteria for reuse, redeployment or other appropriate onward use before equipment is removed.
5. What evidence will we need afterwards? Agree requirements for security, compliance, financial, asset and sustainability reporting at the beginning rather than attempting to reconstruct them at the end.

Answering those questions early can influence the transformation itself. Migration sequencing may help preserve the value or reuse potential of equipment. Particularly sensitive systems may require additional controls, while assets intended for redeployment may need to be handled differently from those destined for recycling.

In that context, decommissioning becomes less of a clean-up operation and more a part of wider infrastructure governance.

Plan the exit alongside the destination

AI, cloud adoption and infrastructure modernisation will continue to reshape data centres across the UK and Europe. As infrastructure requirements evolve, organisations will need to give greater consideration to the volume and complexity of equipment being displaced.

The challenge is not simply how quickly organisations can deploy the infrastructure they need next. It is whether they can maintain the same standards of security, accountability and governance over the technology they no longer need.

Every transformation programme should ask two questions from the outset: what are we building for the future – and what is our controlled, secure and sustainable plan for everything it replaces?

The exit strategy deserves to be considered at the same time as the destination.
