Edge to X is not a lift-and-shift, and the proxies will tell you why

Overview

Apigee Edge to Apigee X is the migration most Apigee customers are either doing or postponing. AceMQ does not run the platform — we plan and execute the customer-side migration: proxy compatibility, networking model changes, KVM and cache behavior, analytics differences, and the cutover itself.

Challenge

The organization had several hundred proxies on Edge, many using features whose behavior differs on X — key value map scoping, cache policies, virtual host and TLS configuration, and monetization-era artifacts. An initial attempt to import proxies wholesale produced deployment failures that gave no clear signal about which differences mattered.

Environment

Apigee Edge with proxies spanning partner-facing and internal APIs, migrating to Apigee X with a redesigned networking and TLS model.

Approach

AceMQ inventoried and categorized every proxy by which X-incompatible constructs it used, then migrated in waves ordered by risk rather than alphabetically. Each wave ran in parallel with Edge behind a traffic-splitting front door until parity was demonstrated on real traffic.

Solution

• Inventoried all proxies, shared flows, KVMs, and target servers, categorized by X compatibility
• Rewrote policies and KVM scoping where Edge behavior does not carry over to X
• Redesigned the networking, virtual host, and TLS termination model for the X environment
• Migrated in risk-ordered waves with traffic splitting and per-wave parity validation
• Mapped Edge analytics reports onto their X equivalents so reporting continuity was preserved
• Defined rollback per wave so any single wave could revert without touching the others
