# Adobe Migration Deep Dive ## Overview Comprehensive guide for three major migration scenarios: (1) legacy Adobe API consolidation into Firefly Services, (2) migrating from competitor document/image APIs to Adobe, and (3) JWT credential migration to OAuth Server-to-Server. ## Prerequisites - Current system documentation with API inventory - Adobe Developer Console project with target APIs - Feature flag infrastructure - Rollback strategy tested in staging ## Instructions ### Migration Type Assessment | Type | From | To | Complexity | Duration | |------|------|----|-----------|----------| | Auth migration | JWT credentials | OAuth Server-to-Server | Low | 1-2 days | | API consolidation | Separate PS/LR endpoints | Firefly Services SDK | Medium | 1-2 weeks | | Competitor replacement | Cloudinary/imgix/PDFTron | Adobe APIs | High | 4-8 weeks | | Full replatform | Custom pipeline | Adobe App Builder | High | 2-3 months | ### Scenario 1: Consolidate to Firefly Services SDK The Photoshop and Lightroom APIs were previously separate. They are now part of Firefly Services with a unified SDK: ```typescript // BEFORE: Separate clients for each API import { PhotoshopAPI } from 'some-old-photoshop-client'; import { LightroomAPI } from 'some-old-lightroom-client'; // AFTER: Unified Firefly Services SDK import { PhotoshopClient } from '@adobe/photoshop-apis'; import { LightroomClient } from '@adobe/lightroom-apis'; import { FireflyClient } from '@adobe/firefly-apis'; // All use...
