In today's dynamic business
environment, it is critical to know when to adopt
new technology and when to
keep current applications in place. The challenge
is to understand when doing business in the current
environment has become more painful than the task
of migrating to a new environment. Legacy Migration
is
an opportunity to align business processes more
closely with new IT capabilities.
The scope of the migration can vary: porting
of legacy application software (3GL code, user-interface,
middleware), database conversion, web-enabling,
or turnkey migration to a new operating system
or
platform.
One can web-enable the legacy OLTP applications,
e.g. replacing the middleware by a J2EE or Windows
compliant application server and redesign the
user-interface with OO (.Net Apps, Java, VB
or C++ etc.),
making the application available for enterprise
application integration and e-business.
