Hello we are having a code upgrade on NS960 for flare it is from 4.30.0.5.512 to 4.30.0.5.524 and for DART it is from 6.0.41-3 to 6.0.61.0. What are the precautions we need to take before the upgrade. I know there will be down time for shares and exports on data mover(rebooting all at a time). After the reboot will the NFS exports will be in hung state do we need to reboot and then manually mount the exports again? In case of CIFS we use AD group policy script in order to map the shares to users. What precautions we need to take in case od CIFS?
