Fermilab has decided to replace Enstore, its locally developed tape management system, with CTA. Fermilab runs two Enstore instances: CMS with a small, dedicated tape buffer and Public operating like an HSM with tight integration between dCache and Enstore

This talk will cover:

* Metadata migration from Enstore to CTA * Results of dCache integration with CTA at FNAL * Performance testing and monitoring * Thoughts on integrating Enstore's "small file aggregation" (SFA) feature (Public instance only) * Timeframe for migrations

Reading of physical Enstore tapes is discussed in Jorge's OSM talk.
