Modernization & application migration

Developing old software requires understanding what it involves. Dtouch prepares for takeovers and migrations by connecting data, processing and the people who use the system.

Reconstitute useful functioning

We examine screens, data, documents and exchanges with other tools. Users help find rules that have accumulated in the software.

The work can rely on the analysis of formats and flows when the documentation is incomplete. This understanding makes it possible to distinguish which functions should be retained from those which should be revised.

Choosing a recovery trajectory

The migration can relate to a database, an engine, an interface or the execution environment. We identify the components to evolve and the steps that can be prepared separately.

Experience with FileMaker, 4D environments and platform redesigns brings attention to data correspondences and dependencies between tools.

Check data and results

Reworks are checked on representative cases: identifiers, relationships, histories, calculations and documents. Deviations must be able to be explained and corrected before a changeover.

Testing is not limited to imported volume. They follow the paths that use the data and check the consequences of an update or restart.

Preparing for the transition with exploitation

Commissioning requires clear responsibilities, verifications and a possibility of recovery adapted to the context. Stakeholders need to know which environment to use and when.

Transmission accompanies change: new benchmarks, documentation of exchanges and monitoring of initial production returns.
