We have migrated old technology code into latest technology ones. We understand various methodologies that can be put to use during migration activity. One such migration scenario, but not limited to is VB to VB.NET.
We do understand the key parameters such as size of code, usage of third party DLLS, volume of custom classes, database linkages and their impact in migration activity. These parameters do play key role in defining the migration approach. We need to define whether tool based migration is possible or manual migration is required or a combination. Sometimes part of the application requires redevelopment. But, the best approach can be identified based on the analysis of As-Is and requirements of To-Be.
