Assuming the employer/employee relationship is healthy, I give the customary 2 weeks, but always allow for up to 4 additional weeks of off-site 1099 consulting and communication. This can be especially helpful when transitioning a large codebase, or really any suitably complex project, where some of the undocumented "lore" isn't readily apparent to either party until after the formal transition effort is already well underway.
