Start with workload disposition
Group systems into retain, retire, replace and relocate. Do this before inventory turns into a shopping list.
Test the facility case
Compare remaining lease term, power and cooling headroom, resilience gaps and hands-on support. A good platform in the wrong facility is still a poor investment.
Price the whole change
Include licensing, migration effort, outage planning, temporary overlap, data transport, installation and support—not only hardware acquisition.
Make reversibility visible
Identify which decisions lock the organization into a facility, platform or vendor. Preserve options where the cost is reasonable.
Sequence around business risk
Move low-risk services first, protect shared dependencies and define rollback criteria before the change window.
Compare the choices on the same basis
Use a common evaluation period and a consistent set of cost categories. Include installation, migration, support, licensing, facility charges, temporary overlap and eventual retirement. Record where an estimate is uncertain instead of presenting a precise total built on weak inputs.
| Option | Question to resolve |
|---|---|
| Retain | Can the current equipment remain supportable for the intended period? |
| Refresh | Does the existing location still fit the workload and operating model? |
| Relocate | Can the destination meet requirements without creating avoidable migration risk? |
| Consolidate | Which dependencies and failure domains would become shared? |
| Retire | Have the business owner and data owner approved removal? |
Build the change plan before the order
List shared services, physical connections, application owners and recovery dependencies. Decide what can move together and what should be separated. Document the conditions for stopping or reversing a change, including who can make that call.
Hardware retirement also needs its own work package. Include asset ownership, data-handling requirements, chain of custody, approved disposal methods and the evidence the organization must retain. Do not assume equipment removal also proves that the data has been handled correctly.
Use this brief as a starting point for planning. Confirm equipment and facility requirements with the relevant suppliers and qualified specialists.
