“ The solution of eranea is the best answer to the
priorities of CIOs: massive cost cuts and moderni-zation
of IT systems ”
The migration solution of eranea
relies on:
u The 100% automatic conversion
of original programs to maintai-nable
Java source code.
u The guarantee of fully identical
functions in the converted
applications.
u The continuity of maintenance of
original system without interrup-tion
during migration project.
u The absence of big bang, thanks
to cohabitation of new and old
system.
u The progressiveness of migra-tion
thanks to sharing of same
database.
u The tailoring of project execution
to your needs.
It is supported by a set of Java
products allowing efficient migra-tion
and subsequent operations:
u Tool to analyze and manage
software assets.
u Continuous integration system
all along entire chain, from
automated transcoding to de-ployment
on application servers.
u Module for creation and mana-gement
of automatic execution
of non-regression tests.
u Complete environment for effi-cient
pre- and post-migration
development.
u Monitoring tool for real-time
supervision of migrated
applications.
u Convert automatically your legacy programs (Cobol,...) to maintainable
Java source code.
u Implement a runtime environment reproducing exactly all the legacy
batch and transactional functions (CICS®, SQL, …).
u Rely on a set of Java products optimizing the migration process and
then the daily operations.
eranea fosters the smooth migration of your mission-critical
applications towards Java, Web 2.0 and SOA

Migration towards an open and
standard platform brings cost
cuts up to 90% when compared
to a mainframe.
Resulting recurring savings often
amount to millions of USD/EUR
per year.
Most often, achieved savings
finance the project and then
provide an extremely quick
return on investment.
Significant cost cuts are already
achieved over the first months of
migration by progressive stop of
legacy subsystems.
The migration towards Linux/x86
servers produces savings related
to both core supplier and third
parties.
Massive reductions in operations costs
The transcoder of eranea ensures
a fully identical conversion of your
applications to Java from a func-tional
standpoint.
The character-based interface
screens are mutated to identical
web-based pages, eliminating
training needs for end-users.
The Java source code and web-based
screens can be taken over
by your teams for further functio-nal
innovation.
To suit a SOA architecture, the
transcoder of eranea can generate
a web service for each legacy
transaction or process.
The integration of a suite for
Business Process Management
can then be achieved rapidly.
The move toward a J2EE-com-pliant
application server becomes
natural.
The solution of eranea allows
you to host your applications in
a private or public cloud.

eranea fosters an incremental and
smooth migration method elimina-ting
needs for big-bang.
The new system is able to run in
parallel with the existing one by
sharing the same database.
The migration happens without
blocking maintenance of the
legacy application.
The Java programs are conti-nuously
and automatically
updated with the last changes
on Cobol source code.
Non-regression test tools conti-nuously
validate the coherency
between the old and the new
system.
The pace of migration for indivi-dual
end users can be freely
defined.
The solution of eranea protects
the numerous men-years invested
in the development of your
applications.
The transcoder of eranea preserves
the functions in your applications,
but also coding syntax and algo-rithms.
The intelligence included in your
original application code is trans-ported
to Java programs ensuring
the perenniality of your business
know-how.
The identical structures ensure the
adhesion of your developers. They
perceive the continuity of their role.
After migration, maintenance
can be pursued either in Cobol
or in Java.
Protection of investments and business competences
Human and organizational impacts

without big-bang
u Continuity of application

u Intrinsic absence of risks
u Perenniality of your
business competences
u Adhesion of your developers

u QUICK AND MASSIVE COST CUTS
u No big-bang
u Multiple project references
u Innovation and optimization
u Complete and integrated
solution
u Cost cuts amount to millions on IS budget
Savings and ROI visible after only a couple of months of migration
thanks to progressive stop of historical subsystems.
Reductions up to 90% for hardware and software costs.
u Migration via small steps without risks
No big-bang !
Natural cohabitation between old and new system over the course
of migration.
Migration of end user happens smoothly at best suited pace, in small
reversible steps and without bumps.
u Multiple references exist: administration, media, finance, software
vendors
u The new technological context extend the life of the application
Java allows significant further technological and functional
improvements.
It brings new development philosophy and methodology.
x86/linux infrastructure is currently the optimal choice among
all possible Java platforms.
A private or public cloud can host the migrated application.
