Feature Sunset Checklist for Product Managers

For paid features used by customers on active contracts, give at least 90 days notice. For free or beta features, 30 days is standard. If the feature is contractually guaranteed, consult legal before setting a date. The goal is giving users enough time to evaluate alternatives, migrate their data, and adjust their workflows without feeling rushed.

Use three criteria. First, does the feature create ongoing maintenance cost even with zero investment (security patches, infrastructure, support tickets)? If yes, sunset it. Second, does the feature conflict with the product direction or confuse new users? If yes, sunset it. Third, is it simply not getting new development but stable and low-cost? If so, deprioritize and leave it alone. Use the [RICE framework](/frameworks/rice-framework) to score the value of removing versus maintaining it.

Start with data and empathy. Show the customer their specific usage, explain the rationale, and present the migration path. If the alternative genuinely does not cover their use case, negotiate a timeline extension or fast-track the missing capability. In rare cases, maintain the feature for a single customer under a custom agreement with a sunset clause. Never reverse the decision publicly, as it undermines your credibility with every other customer.

Gradually. A staged approach reduces risk and gives you checkpoints to measure impact. The recommended sequence is: announce, disable new activations, move to read-only, then remove. Each stage should have a monitoring period. If support tickets or churn spike unexpectedly at any stage, you can pause and investigate before proceeding. Track [feature adoption](/glossary/feature-adoption) of the replacement to confirm users are migrating successfully.
