Legacy applications
are frequently large, monolithic and difficult to
modify, and scrapping or replacing them often means
reengineering an organization’s business processes
(workflow) as well. Legacy migration is about retaining
and extending the value of the legacy investment
through migration to new platforms.
Re-implementing applications on new platforms in
this way can reduce operational costs, and the additional
capabilities of new technologies can provide access
to valuable functions such as Web Access to the
client. Once migration is complete the applications
can be aligned more closely to current and future
business needs through the addition of new functionality
to the migrated application.
The goal of Ewak’s Power Migrator™ , migrating
PowerBuilder™ to J2EE addresses the above business
need.
J2EE defines the standard for developing multi-tier
enterprise applications. The J2EE platform simplifies
enterprise applications by basing them on standardized,
modular components, by providing a complete set
of services to those components, and by handling
many details of application behavior automatically.
Portability and scalability are also important for
long-term viability. Enterprise applications must
scale from small working prototypes and test cases
to complete 24 x 7, enterprise-wide services, accessible
by tens, hundreds, or even thousands of clients
simultaneously
Ewak’s Power Migrator™ enables the legacy
PowerBuilder client Server application’s business
code to be ported to the middle tier as components
for portability and scalability
