8x00 Enterprise Virtual Array updating product software guide (XCS 6.200) (5697-7958, February 2009)

2 Pre-upgrade tasks

There are a number of necessary tasks that can be performed prior to beginning the upgrade. Performing

these tasks prior to, rather than during, the upgrade minimizes the time required to perform the XCS

upgrade procedure.

The required tasks differ depending on your system conﬁguration. They focus on upgrading components

to ensure they meet the supported conﬁguration for XCS 6.200. Table 4 provides a checklist so you

can track your progress as you perform these pre-upgrade tasks.
