Legacy Migration with Custom AI Document Intelligence

Scenario

A team migrates legacy databases to Alibaba Cloud via ECS snapshot staging through OSS into RDS, then trains domain-specific embedding models on PAI to power a Bailian OCR document pipeline with hybrid OpenSearch retrieval and AIRec personalization—creating a full modernization path from legacy data to custom-trained AI search.
