Source note · Unified CM release trains and lifecycle dates
The Unified CM 12.5 and 14 Last Dates of Support fall about two years after their end-of-sale dates (Aug 31, 2023 to Aug 31, 2025; Apr 7, 2025 to Apr 30, 2027), matching Cisco's two-year TAC window for application software. Expect any future Release 15 LDOS to land about two years after its EoS.
