A 1.7 working copy will have a .svn/wc.db file in the root of the
working copy.  A 1.6 working copy will have a .svn/entries file in every
versioned folder.

It's not possible to upgrade a subfolder, only an entire working copy
can be upgraded.  The upgrade process writes all the 1.7 .svn data, for
all subfolders, into a temporary location before deleting any of the 1.6
data.  The final step of the upgrade is to move the new 1.7 .svn data
into place and to remove the old 1.6 .svn data.

The error message you showed happens while writing the 1.7 .svn data, so
it happens before any of the 1.6 .svn data has been deleted from the
subfolders.  If you have versioned subfolders that are missing .svn
folders it is likely that something other than the upgrade was

A 1.7 server supports earlier clients and doesn't care about the working
copy format.  If you are unable to use the working copy it's because you
upgraded the client, not the server.
