 NSO Setup details:172.20.63.189 (cnctest/Ovatest123@)Note: There are existing services on this NSO, if I revert it back to M5, NSO comes up again.it took serveral hours but ncs service came up even it showed timeout error earlier. Is there a timeout constraint for scale. Before starting NSO after the upgrade, have you added --ignore-initial-validation to the start scriptStart NSO with package reload + force flag + --ignore-initial-validation Please check the below steps1. sudo /etc/init.d/ncs stop2. Add --ignore-initial-validation flag as shown below in start() functionsudo vi /etc/init.d/ncs=========================......start() {    echo -n $"Starting $prog: "    . $ncsdir/ncsrc    NCS_CONFIG_DIR=${confdir}    NCS_RUN_DIR=${rundir}    NCS_LOG_DIR=${logdir}    export NCS_CONFIG_DIR NCS_RUN_DIR NCS_LOG_DIR    $ncs --cd ${rundir} ${heart} ${conf}    RETVAL=$?    echo<ol>[ $RETVAL = 0 ] ;; touch /var/lock/subsys/ncs    return $RETVAL}......==========================Change it to==========================......start() {    echo -n $"Starting $prog: "    . $ncsdir/ncsrc    NCS_CONFIG_DIR=${confdir}    NCS_RUN_DIR=${rundir}    NCS_LOG_DIR=${logdir}    export NCS_CONFIG_DIR NCS_RUN_DIR NCS_LOG_DIR    $ncs --cd ${rundir} ${heart} ${conf} --ignore-initial-validation    RETVAL=$?    echo[ $RETVAL = 0 ] ;; touch /var/lock/subsys/ncs    return $RETVAL}......==========================</ol>3.

Estimating approximately 8-9 hours for the upgrade.
