connect-migration-store

A session store wrapper for Express/Connect that enables zero-downtime migration from one session store to another. Version 1.1.4 is the current stable release with low release cadence. It wraps two stores (e.g., Redis and DynamoDB) and transparently forwards reads and writes to both during migration. Unlike manual migration scripts, it preserves user sessions without forced logout. ESM-only not supported; CommonJS only.
