Upgrade - How to roll back



  • I am currently running 2.4.3-RELEASE-p1, and I see that older versions are no longer available, so I can't reinstall the old version.

    Can someone please give me some suggestions on a fallback strategy in the event my upgrade kills my router. If that happens I will be cut off from the internet completely, so it is essential that I have whatever I need to get back up and running immediately.

    Is it safe to create a tar.gz file of / - it's not an atomic transaction? If so what about restoration?

    Hello,

    • make a backup (Diagnostics/Backup&Restore/Download configuration as XML)
    • download 2.4.4_p1 image and make bootable USB stick. With 2.4.4_p1 release, FAT32 partition will be created on USB stick, so you can put your XML configuration file into this partition.
    • upgrade and check if it works
    • if it isn't, reinstall from USB stick

    Thanks @asamat - Hopefully I won't need to roll back, but at least I know one way to do it.

    The system came back up. Only thing is the console froze with:
    Booting
    |

    The little spinner didn't spin and I got no boot messages.
    I did a second reboot and see if the issue would clear, but unfortunately it didn't.

    I'll post this as a separate thread.
