Mixed — varies by part numberCisco ISR 800 Series has mixed lifecycle status — some SKU groups are already past Cisco end of service while others run until Jan 2027. Confirm the exact part number before any support or refresh decision. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure. Cisco’s named migration path: Cisco IR1101 / Catalyst IR1821 Rugged Series / Cisco ISR 1100 / 900 Series.

Options from here
Mixed — varies by part number3 Cisco ISR 800 Series part numbers are past Cisco end of service while 5 remain supported (to Jan 2027). For the past-EOSL units, these are the usual paths:
Keep it in production past the OEM cutoff with an independent maintainer.
Buy spares now, while units still circulate on the secondary market.
It is unsupported today — set a migration timeline and budget.
Low-criticality role — document the risk, harden backups, retire on your terms.
Independent and informational — EOSL.ai sells no hardware or maintenance and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the asset's role.
