How to change the SCAN Listener Port After Installation?

Modify SCAN listener port:
$ ${GRID_HOME}/bin/srvctl modify scan_listener -p <new-SCAN-port>

Restart SCAN listener so the new port will be effective:
$ ${GRID_HOME}/bin/srvctl stop scan_listener
$ ${GRID_HOME}/bin/srvctl start scan_listener

Confirm the change:
$ ${GRID_HOME}/bin/srvctl config scan_listener

Cheers !!!!!!!
