Coexistence: Preserve or migrate a Version 5 gateway
Web services gateways running on WebSphere Application Server Version 5 application servers can, subject to certain restrictions, coexist with Version 6 gateways and be part of Version 6 cells.

To help you choose whether to preserve or migrate your Version 5 gateways, this topic explains the restrictions to gateway coexistence and the approach taken to gateway migration.
