Storage migrations made simple.

Minimizing the impact of data migrations on business operations is a critical

part of the data center manager's job. Studies have shown that technology

refresh - defined as replacing an older server or storage array with a new

one - is the primary driver of data migration. Storage hardware and server

replacement, as well as the expiration of storage equipment leases, means that

storage managers have to move data on a regular basis. Moving data for tech-

nology refresh can be problematic, however, due to application availability

requirements, incompatibilities between source and target systems, and time

and budget constraints. While technology refresh projects are typically sched-

uled to be performed during off-hours, today's 24x7 environment means that

applications need to stay online, even during off-hours.

New software allows nondisruptive migration, meaning that applications

remain online during migration, without significant performance delays. And

reliable methodologies that help plan, migrate and validate data migrations

can enable customization, speed the process and ensure data integrity - simplify-

ing the technology refresh process.
