Updates and upgrades of any software are a headache for most companies. First of all, there is no need to do this, unless the versions are becoming completely obsolete. And secondly, there is no efficient methodology to carry out these projects.
In AJAF We are permanently on the train of update projects. This has forced us to generate a repetitive process, with an optimized methodology, taking full advantage of the tools and practices that software developers make available to their clients.
