Technology and Component Obsolescence
Why unsupported equipment can create operational risk before it physically wears out.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Why unsupported equipment can create operational risk before it physically wears out.

Migration planning reduces the chance that an emergency failure becomes an unplanned modernization project.
What to review
Useful reviews usually combine service criticality, dependencies, condition, capacity, maintenance, alternate arrangements, restoration time and clear ownership rather than relying on one isolated metric.
