Many thanks, Cory,
I see the dup-installer folder has a file called dup-database__12345etc.sql. That looks promising at least.
However, given that it failed miserably when I tried to run the installer, telling me I had to install it manually, is there any documentation on how to manually install? I need to install it as a “staging” site in a sub-folder, NOT in my main home folder just yet.
Sorry to be a nuisance but I would appreciate any help to get the thing going.
Thanks,
Gordon
