Is there a better way? I think this will be a nightmare. You are going through five versions without active repositories, and with all the orphaned packages (which might include libraries you need), the name changes, the structural changes, etc. Is there any way that you can install the new server in parallel with the existing server? That is, carve out some room on the hard drive and do a fresh install of f26. Or purchase a new drive, install it on the server system, and do a fresh install there. Then you have a working backup to fall back to if f26 is too much to deal with at any time. And, you have the customized version still there to map into the new version, as you discover discrepancies over time and at your leisure. Good opportunity to document all that customisation, too. :-) Failing that, could you clone the existing f19 server installation to another system and do a test upgrade run on the clone before risking your production server? If the test upgrade works, you could then just rsync back to your production server, and be in business again. Well, there would be some tidying up to do in the boot process (fstab, grub.conf, etc.), but everything else should just work. And if it fails, you've dodged a bullet. There would have to be a *lot* of difficult and obscure customisation before I would consider going the path you are thinking of. And it is very risky if the server is at all critical. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
