Comparing text tools
To upgrade your application code to a new version of Microsoft Dynamics NAV, you have to compare your customized application code with the old original standard application code to determine which customizations have been made and where they have been made.
A second comparison has to be done, between the old original standard application code and the new original standard application code to determine what differences exist between these two versions, so that we can decide whether the old customized objects can still be used (if the original object hasn't changed) or if the customization has to be manually carried out to the new version of Dynamics NAV.
There are several generic compare text tools that you can use for this purpose. A web search will present you with several tools that you can use. We will not explain any of these tools here. We just want to point out that you can use any of them for application code upgrade purposes.
