My reading of the OP was that someone had probably seleected a sub-folder for conversion and
that may well have succeeded.  Seeing as you can take a 1.6 sub-folder and effectively make
it a top-level folder, this makes sense to me?  Or does the upgrade code crawl upwards to
see if folders above are versioned?

The error then happened when someone tried to convert the real root folder, where one of the
subfolders was already converted...
