3.4 Precautions on use

For a J2EE server that is already set, you cannot switch it from recommended mode to V9 compatible mode, or switch from V9 compatible mode to recommended mode. Execute the unsetup operation for the J2EE server, and then set up again.
To delete only the logical J2EE server from a system built by using the Smart Composer functionality and management portal, and then create a logical J2EE server with the same real server name but in a different mode, use the cjsetup command to execute the unsetup operation for the J2EE server before creating the logical J2EE server.

For details on the cjsetup command, see cjsetup (set up or unsetup J2EE server) in 2.2 Commands used for operating J2EE servers in the manual uCosminexus Application Server Command Reference Guide.
