Upgrading 64-bit NanoBSD from 2.3 to 2.4

  • Rebel Alliance Developer Netgate

    We now have a procedure published on the wiki to upgrade in-place from a 64-bit 2.3 NanoBSD installation to 2.4.

    The process cannot be fully automated in a reliable way, but we have both a fully manual and a script-assisted method on the wiki:


    We have tested this a number of times on different setups with VMs and real hardware and it works well.

    As a bonus, you will also end up with an installation which uses the full size of your media. If you had a 4GB NanoBSD on an 8GB disk, on 2.4 it will be a single slice using all 8GB at the end of the process.

    The procedure does not create any swap space, however. If that is a requirement, reinstall to the disk with the 2.4 installer.
