Upgrading a Grails app from version 1.3.7 to version 2.4.4

Hello Grails users,

We recently worked on a grails project which needed to upgrade in terms of code base and tests. The basic idea was to get the app in working state after upgrading the underlying powerful engine known as Grails. But it was a serious business, as the app contained 654 files with 1,00,833 LOC (which includes tests and doesn’t includes JavaScript code).

It was quite a task to achieve as most of the functionality was driven by Knockout.js and GSPs.

So we’ll talk about the importance of tests and how they helped us to upgrade from legacy Grails 1.3.7 to Grails 2.4.4, and the whole story is here at DZone. You can also find the equivalent Markdown version at Github.
