There are times when building virtual machines in multiple environments that you might want to have different images so that you can use another platform. More common is the case when you have a format that you created or downloaded and it does not match the tool you are trying to use. An image conversion tool is perfect for such a case! The tool I use often for accomplishing this is Starwind V2V Converter From Starwind Software, available at https://www.starwindsoftware.com/.

Note that you will be required to register and the application runs in Windows. Once you have downloaded the software, install it and then run the program. It is an easy-to-use tool: you select the file image to convert by navigating to it. Following this, the tool will display the options for the format output. An example of this is shown in the following screenshot:

Once the output format has been selected, the conversion process will run, and once it is finished, you only need to go through the steps that we covered before for the tool that you have chosen. As discussed, the tool works very well and saves a lot of time. It also provides you with the ability to pick and choose any platform that you prefer for building your pen-testing environments.
