UPGRADE SERVERS THAT HAVE BECOME UNRELIABLE OR CANNOT BE
MAINTAINED
Most organizations do not service or repair their own server hardware. Instead,
they rely on annual maintenance agreements between the business and
the server vendors (or even third-party vendors). As years go by, parts become
scarce and vendors often focus their service organization on more recent product
offerings, charging far more money to service older systems. Eventually, the
cost of maintenance contracts becomes prohibitive and an upgrade to a later
system is easier to justify in lower service agreements and troubleshooting/
maintenance costs.
