Thanks for that; I assume that I would have to carry out the following plan of action?

• Copy the files on top of the existing installation - with the exception of the vars_* files
• Run some script ("cgi-bin/ubb_upgrade.cgi"?) to update it to 6.7.2

Would this upgrade a 6.2 or 6.3 board or do I need an intermediate upgrade?

If you would have looked in the classic forums you would have found this.
http://www.ubbcentral.com/support/install.php?product=UBB.classic .
This should answer your question.
Download the most current version in the members area.
Since classic is not supported anymore there would not be a special upgrade zip. Just exclude the files stated in the document.

Thanks for enlightening me, Rubens. I guess I should have looked in the Classic category first!

Note to Groupee: Might be helpful to change the read me note in the UBB Classic ZIP file to state that the upgrade is the same as the full version minus the vars_* files, rather than tell them to download the "upgrade" ZIP...
