Vex ships cross-store vector migration tool

Vex is a cross-standard vector DB migration tool from Vektor Memory that exports, imports, and migrates agent memory between vector stores through an open `.vmig.jsonl` interchange format. It supports moving data across backends like Vektor, Pinecone, Qdrant, Chroma, Weaviate, and pgvector, with options for direct migration, re-embedding, and embedding projection when dimensions or models differ. The project is open source under Apache 2.0 and is positioned as a way to avoid one-off migration scripts whenever you switch vector infrastructure.

// ANALYSIS

Strong utility release for anyone who has been stuck hand-copying vector data between incompatible stores.

–Solves a real pain point: vector DBs do not interoperate cleanly, so migration is usually bespoke and fragile.
–The `.vmig.jsonl` format is the key idea here: simple, portable, and designed to preserve text, metadata, and embedding context.
–The connector list is already useful, especially for teams moving between local and hosted stores.
–Re-embedding and vec2vec projection make it more than a dumb export/import wrapper.
–Best fit is AI agent memory and RAG infrastructure teams, not general-purpose database users.
