Right, running 1.7.8 with new database formate to date. All going smoothly.
Just install a fresh xibo file system latest version in adjacent folder and point it to old database copy.
You will be prompted for a database format upgrade not backwards compatible.
And a message if you want to get rid of install.php. Why do I need to remove install.php anyway?
Dont forget to copy your old xibo cache over the new file system otherwise you will miss some media!!! Youi can not do this when fresh instaaling a new Xibo because the install script wants to see a non existing empty cache directory, hence do it afterwards!
