If this is a Linux based OS, a reinstall is rarely needed. There are many ways to migrate it from an old drive to a new one. Cloning the old one to the new and expanding the main partition to occupy the extra space is one. A cleverer way would be to move it to LVM so that next time you'll have options for expanding by adding more drives. If the new drive is double the size, you could clone, boot from the new then setup LVM in the empty space, migrate the OS to it, then boot from that, followed by reclaiming the cloned space and adding it to the LVM.
There's nothing particularly wrong with running it in a VM as you suggested either. Or you could run the new install in a VM then install it in the server once ready.
