I tried from Upgrade Version 1.7.3 to 1.7.7, must i Upgrade Version to Version or can i skip the Version 7.4. and more?
We have the followed the Upgrade Instructions -> http://xibo.org.uk/manual/en/release_notes_1.7.7.html#upgrade .
But we get always Mysql Error’s about Constrains. The Error exists in every Upgrade by us.
What we do wrong?
