Include: 1) Usage analysis to understand impact scope, 2) User segmentation based on feature dependency, 3) Communication timeline and messaging by segment, 4) Alternative solution or migration path, 5) Technical implementation plan with phases, 6) Internal training for customer-facing teams, 7) Success metrics for a smooth transition, 8) Feedback collection mechanism during the process, 9) Contingency plan for users with critical dependencies, and 10) Post-deprecation support strategy.
