Upgrade Elgg from 1.8.19 to 1.12.9

Last updated by Paul Neilson Comments (1)

Just looking to see if it's possible to upgrade Elgg from 1.8.19 straight to 1.12.9? or is this too much of a quantum leap? What issues would probably happen?

  • No. Not possible. Upgrade one minor release at a time, i.e. 1.8.19 to latest 1.9, then to latest 1.10 etc.

    From 1.10 to 1.12 it "might" work but I don't recommend it just to be on the safe side. If you leap over a minor release the upgrade might get stuck and in the worst case leaves your database in a broken state.
