12 AAA
Financial Services Company is performing implementation
planning for a core switch upgrade. The company has 200 financial
software programmers that work billable hours during the week. They
have critical, scheduled money transfer transmissions that
occur at
hourly intervals every night. There are two, two-hour long IT
maintenance windows scheduled for software upgrades, one on
Saturday and one on Sunday. The bank advertises online banking as
available 24 hours on business days and 21 hours on the weekends.
However, a network upgrade that is necessary to replace some
switches is expected to take four hours. Because of rack
constraints, this time includes three hours to remove the old switches
before the ew switches can be installed and one hour to test the
logical configuration. How should the implementation scheduling be
handled
#Coordinate and publish an
eight-hour downtime incorporating the Saturday window. This will
allow four hours for installation and logical testing, one hour for
troubleshooting and decision,
and three hours to roll back to the
previous configuration if the new switching cannot pass the logical
testing. Defer any software upgrades until the new network is proven to
be working
correctly with the old software.
