Migrating from per-environment IP allowlists

Lesson 101 of 201 · 11 min

The older per-environment mechanism and its deprecation. Inventory existing per-environment allowlists across the estate, consolidate them into a domain-level perimeter, test EVERY environment, then remove the old configuration. INVENTORY BEFORE CONSOLIDATING. Different environments may have accumulated different allowlists, and merging them naively either locks somebody out or opens something up. Both directions are failures and only one of them is noticed. Test every environment after consolidating, not just one. This is a migration with a deadline attached. Do not discover it late.
