Direct answer. Workstations 3–5 years. On-premise servers 4–6 years. Firewalls and switches 5–7 years. Wireless 4–6 years. Software continuously. This is a lifecycle guide, not a second Miami page. The work lives on Managed IT Services Miami. Call (844) 919-8534.
Why outdated IT hurts
For a 10–100 person shop, aging gear is not a style problem. It is downtime, patch gaps, and a bill you did not budget. Industry research puts mid-size downtime in the thousands of dollars per minute when the whole floor stops. You do not need that number to be yours. You need a calendar.
Security patches end
Unsupported OS and firmware stop getting fixes. Attackers scan for that. 24/7 security monitoring. When an alert fires, RRG responds — but an unpatchable box is still a hole. See Miami cybersecurity.
Failure risk climbs
Server failure rates rise sharply after year five. Emergency replacement costs more than a planned refresh, and you lose the day.
People wait on machines
Slow boot, crashes, and tickets that never stay fixed. That is hours you already paid for.
Cloud apps feel worse on old LANs
VoIP and SaaS punish latency. Old switches hide that until a call drops in front of a client.
Upgrade schedule by component
Computers and workstations — 3–5 years
Most business PCs are fine for 3–4 years. By year 5, boot times stretch, current Microsoft 365 builds struggle, and hardware errors show up. Replace before failure so you are not copying files off a dead disk.
On-premise servers — 4–6 years
Failure risk roughly doubles between years 4 and 6. After year 5, many manufacturers end standard support, so firmware and BIOS updates stop. A dead server holding shared files or a line-of-business app can stop the company the same morning. Some shops should not buy the next server at all — they should move that workload. Read cloud vs on-premise for small businesses.
Firewalls and network security — 5–7 years
A firewall that no longer receives threat updates cannot see modern attack patterns. Consumer routers are not a substitute. Unsupported perimeter gear is a compliance problem in regulated shops, not just a speed problem.
Switches and routers — 5–7 years
Aging switches become a quiet bottleneck as you add cloud apps and phones. Managed switches with VLANs, QoS, and current PoE are how you keep voice and data from fighting.
Wireless access points — 4–6 years
Wi-Fi 5 gear, dead zones, and no WPA3 are the tells. Coverage and protocol gaps show up as “the internet is slow” tickets that are not the ISP.
Software and operating systems — continuous
Software is not on a five-year cycle. Microsoft ended Windows 10 support in October 2025. A shop still on Windows 10 is not getting security patches. Apps, agents, and firmware follow the same rule: current, or exposed.
What delay actually costs
A 35-person professional-services firm in Miami that waits for a server to die does not get a discount. They get emergency labor, rush hardware, and a day of people sitting on their hands. Unplanned downtime in the thousands of dollars of lost productivity is common even without a ransomware event. Plan the refresh. Put it on a budget line. Then stop treating hardware like a surprise.
Upgrade vs cloud
Replace on-premise hardware
Right when the app still has to live here, or you just bought and need the remaining years.
Migrate the workload
Right for file, email, and most line-of-business apps that already have a cloud version. No next server closet.
Hybrid
Productivity in the cloud, one local box for the stubborn app. More moving parts. Needs someone who can run both.
Lifecycle management
Track age, warranty, and patch status. Replace on a calendar, not after the fan screams.
