The Hidden Costs of
When replacing or consolidating systems and meeting constantly increasing capacity needs,
data must be migrated from one place to another; it’s become a routine task in most IT departments.
However, with business and operational needs dictating that critical systems be available 24/7/365 and
the complexity that results from non-commoditized and heterogeneous environments, data migration
has become a task that is both increasingly important and increasingly difficult.
This white paper will outline the factors that are driving data migration and examine the hidden
costs that may be encountered when data is moved.
In most businesses, data migration has become routine necessity and is something that
IT managers must deal with on a regular basis. But, as operational and business needs often
demand that mission critical systems, such as e-mail and web servers, be available 24/7/365,
the windows during which data can be migrated are often small. To add to the problem, most
business systems now hold far more data than in previous years and so there is far more data
that must be moved. Furthermore, many databases and information stores are expanding
exponentially resulting in businesses having to expand their storage capacity with increasing
frequency, and therefore migrating their data with increasing frequency.
In short, businesses are finding that they have more data to move and must move that
data more often and much more quickly.
To further add to the problems, the process of migrating data has become ever more
complicated. Increasingly, data needs to be migrated among distributed, heterogeneous
systems. Data might need to be moved from a physical source to a virtual target, or from a
virtual source to a physical target, or migrated to a target that has diss
