Upgrading large complex systems is a CPU and memory intensive process. You will want to provision a workstation accordingly. A "big" developer workstation is recommended.
A number of executable programs are installed by the gmStudio installer. The most important ones are the following:
Deploy.exe: a "shell interpreter" utility that deploys translation results in target folders and files.
gmStudio will integrate with a number of other programs to help you complete your upgrade effort. These external tools should be properly installed on the Migration Lab machine.
You can use the Configuration\UserDefaults dialog to set most of your settings. In some cases you may need to modify the application configuration file, gmStudio.cfg, so that gmStudio can find and run the external tools in your environment.
Programmer's Text Editor: your favorite text editor. We typically use Notepad++.
