Most 2027 conversations start with the deadline and stop there. The useful question is the reverse one: given your approach, landscape size, and custom code, when is the last responsible moment to start? Everything before that date is optionality; everything after it is risk you are accepting. For the full picture of what ends in 2027 — and what genuinely does not — read our SAP 2027 deadline guide. If the math says you will not make it, staying on ECC longer is a legitimate, plannable choice — see ECC extended support planning. When you are ready to move, our S/4HANA migration services start with a readiness assessment, and you can estimate the cost alongside the timeline. Need to bring leadership along? Turn these numbers into a ready-to-send board memo.
