No to your question. However I was under the impression that the svn 1.7 client can checkout from 1.7 and 1.8, however we will not understand 1.8 working copies.
Yes, you can check out the repository ( and takes quite a while) but the real value is to update a single file or commit changes and that is when I get an error like:
svn: E155021: This client is too old to work with the working copy at
'Q:\SVN_DATABASE' (format '31').
I will put in a request to update.
Thanks for you help.
