Software reinstallations and upgrades

Before starting any upgrade, verify that the system is performing properly.
Check the NAC error log and the UNIX system log (when appropriate) to
verify that midnight backups are successfully completed. Schedule an
upgrade to be completed before 11:30 p.m. or started after 1:00 a.m. so that
the regular NAC midnight routines are executed properly.
Refer to the "Software installation overview" chapter, "Backups" section
for information on performing backup tapes.
