1. Move away from unsupported platforms
2. Leverage new capabilities of modern
development and deployment platforms

<VB6>

3. Extend beyond windows clients
4. Deliver new user experience – i.e.
webify/mobilify
5. Centralize management and
administration
6. Improve app security while extending app
reach

comparing paths to app mobility

replace with
out of the box

application
virtualization

migration

rewrite

Does not fit with your
business processes

Very costly. Poor mobile
app experience

Not effective for converting
to new platform

high cost, long projects,
high risk

transposition

rapidly re-architect existing apps to .NET or HTML5

Delivers new code
(e.g. C# and
HTML5), while
mapping key
dependencies and
controls.

Leverages
patented compiler
algorithms to
rapidly move code
from one platform
to another.

New code is of
highest quality –
as if written from
scratch for .NET

Developer guides
process using tools
– refactoring and
re-architecting as
desired.

6. evolve &
improve

start with old application code
Typical VB6 “thick
client” application
Uses ActiveX
objects
ADODB data
connections
VB6 style error
handling
Win32 APIs
Validated and
Tested Business
Logic

translation and compilation
Extends MS Visual
Studio infrastructure
Source-to-source
compiler
Toolkit for
architects/developers to
translate and refactor
application

working with raw code
Raw translated .NET code
provides “surface” on which
to work
Use Transposition toolkit to
make decisions, define
rules, and apply mapping
and refactoring logic

defining a code pattern
Mark a piece of code as in
important “algorithm” in the
application
Defining template for how
pattern should be
implemented in new code
Visit gizmox.com/trans-dev
for video examples of
transposition tools

transposition
Generate new code
applying rules you
have defined on
the translated code
Iterate

working with transposed code
Maintain visual
development
paradigm
Leverages
existing skillsets

C# or VB.NET
Visual Studio
version of choice

running the app
New app deployable on
web server – improved
manageability
Deployable on cloud
Accessible on any
OS/device using HTML5 (or
4)
No client installation

Highly secure

evolve and improve the app
Leverage form
factor designer
Themes and
templates for
common devices

CHALLENGE

 Need to upgrade desktop/windows-based
energy efficiency application
 Data centric – relies on customizable, graphical
views defined dynamically by user
 Desire to convert to SaaS offering based on
Windows Azure

COMPANY OVERVIEW

Limón GmbH is provides energy efficiency
solutions to businesses – from identifying
opportunities to optimize energy use to
implementing customized efficiency solutions.
é.VISOR is an energy monitoring application that
collects energy consumption data and calculates
key energy statistics.

RESULTS





95% of code converted automatically
UI brought to web with no loss of functionality
Deployment on Windows Azure
Total project completed in 1 month with 1
dedicated developer

“Now that we have completed the migration and are
familiar with the application and the code, I can
confidently say that rewriting it would have taken
between 6 and 12 months, and we have done it in
one month.”
