The outage time that
is required for applying a maintenance release varies from site to
site. Installing product updates is only a small part of applying
a maintenance release. When estimating the outage time for your site,
you must also include time for configuring your Web application servers,
restoring customizations, and completing any post-configuration steps
for products at your site. To estimate how long it will take to apply
a maintenance release, identify the steps in the
Additional Configuration Steps for Your Web Application Servers and
Product-Specific Details and Post-Configuration Requirements chapters that must be completed at your site.
