Switching between feature flags tools is generally possible but involves migration effort: exporting your data or configuration from LaunchDarkly, re-importing or reconfiguring in Flagsmith, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Flagsmith on a non-production project first before migrating.
