Legacy Software Support and Migration Services
'Legacy Systems' are easily described as products implemented
in programming languages that have gone out of fashion, such as
VB6, Microsoft Office (Access) 97, Foxpro, or 'classic' Active
Server Pages (ASP). This also includes a collection of languages
that are still 'in production', but are proving to be expensive to
maintain, such as Cobol or C++. Businesses outgrow their
applications and seek to add functionalty, upgrade hardware, and
create new business services. Finding programmers to
maintain the old systems is difficult and sometimes prohibitively
expensive. Our role is to migrate these systems to more
state of the art platforms. Sometimes this is as simple
as upgrading an Access application to SQL Server and Access 2010.
In a mainframe to web situation the database/file system storage
organization has to be reworked substantially, and the user
interface thought out from the ground up.
Users will often ask for a conversion to be done a particular way,
perhaps based on consultant recommendations. In this process
the project may be over-specified, creating limitations that slow
the conversion and add to costs. Special care
has to be used, for instance, in requiring a particular language,
since an old mainframe Cobol application might be converted to C#
for business rules, T-SQL for data manipulation, and Javascript
for client side user interface event handling and validation.
Code conversion deadlines may be mandated by events that are
peripheral to project management estimates: a financial target,
a business merger or market rollout, or a third party interface.
In situations where the timeline appears 'aggressive', the externally
mandated timeline should be left out of project requirements.
Many conversion projects fail because developers are willing to
commit to deadlines they know will be missed. Our planning
approach is based on the idea of small, frequent deliverables.
This means that the user is able to see functional improvements
on a weekly basis, and can compare that to the expected timeline
and cost, and revise either their schedules or the development
commitment accordingly.
