You can move VirtualBox VDI hard drive images from PC to PC or to do a host operating system upgrade.
How to move VirtualBox .vdi to another PC
- Note the important options of your VirtualBox OS instance. RAM size, number of CPU, etc.–perhaps take a few screenshots.
- Install the new VirtualBox software on the new/upgraded PC
- Create an OS instance with the same options as your old VirtualBox OS instance–when the VirtualBox wizard asked to create the hard drive, “use an existing VDI file” and select your old VDI (it will be several to tens of GB in size).
- Start your VirtualBox OS instance and click the “Devices/insert guest additions CD image” to install the latest drivers.
