Replication from Enterprise to Standard edition Can I define transactional replication while the Publisher and Distributor are both Enterprise Edition and the Subscriber is Standard Edition?

What do I need to consider in case it is possible (given I already know about partitioned tables)?
Yes, you can replicate from Enterprise edition to Standard edition.

The only caveat is Peer-to-Peer Replication requires all nodes to be Enterprise Edition, and Web and Express editions are Subscriber only.
