This chapter contains procedures that must be completed before you 
begin the actual upgrade process. These pre-upgrade procedures 
consist mainly of system checks, backups, and various operations 
upon the metadevices of the DNCS. 

The first few procedures of this chapter can be completed before the 
maintenance window begins, while the actual upgrade of DNCS 
software must be completed during a maintenance window. See When 
to Complete These Procedures (on page 13), for a list of those 
procedures that can be completed before the start of the maintenance 
window.
