Amazon Bedrock Managed Knowledge Base migration guide

AWS has added a knowledge base migration guide to the amazon-bedrock skill in the Agent Toolkit for AWS, helping coding agents move customer-managed Bedrock knowledge bases to Managed Knowledge Base. The agent starts with read-only discovery, then, after the user approves a plan, creates the new knowledge base alongside the original or writes an infrastructure-as-code template. The managed service includes always-on hybrid search, a managed embedding model and reranker, ACL-aware retrieval, and agentic retrieval. Managed pricing is $5 per GB per month for storage and $1 per 1,000 retrieval requests, with quotas of 10,000 knowledge bases per account per Region and 200 data sources per knowledge base.
