2 Pre-upgrade tasks

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

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

to ensure they meet the supported conﬁguration for XCS 6.110. Table 4 provides a checklist so you can
