Tips on trouble-free hardware and software implementations Learning how to manage change in an IT environment is a necessity, not a luxury. Rapidly changing business requirements and accelerating improvements in hardware and software drive new and improved products to market in less time than ever before. At some point, every business is faced with having to upgrade their computer systems.
Every business wants the transition from old to new to be as painless as possible.
In hardware terms, an upgrade would be the addition of more memory, CPUs or adapters to an existing system. Upgrades usually don't require long system outages. Migrations are more complicated, and they require additional planning for trouble-free implementation. From an AIX perspective, a computer's system image encompasses the sum of all hardware and software customization, from the operating system, applications, network interfaces and storage media to users and data. The challenge is to move as much of this image to a new system as possible with minimal disruption.
