Question

Answer 1

I success to downgrade svn from 1.8 to 1.7 by following this post: Install a Specific Version of a Tool on OS X With Homebrew。

Uninstall the previous version:

$ brew uninstall svn
$ sudo mv /usr/bin/svn /usr/bin/svn1.8

Find out how old versions are called:

$ brew search subversion
subversion
homebrew/versions/subversion16  homebrew/versions/subversion17

Install old versions：

$ brew tap homebrew/versions

After downgrade, you may encounter the sqlite version error, you can refer this post if it do happen: Subclipse error "svn: SQLite compiled for 3.8.6, but running with 3.8.5"

Answer 2

• Commit any uncommitted work or save uncommitted work if you are unable to commit with 1.8 SVN.
• Delete or rename working directory.
• Uninstall your 1.8 SVN client.
• Install 1.7 SVN client.
• Checkout repo again. Working copy is now 1.7 format

Answer 3

Since both Subversion 1.7 and 1.8 have a single .svn folder in the root directory (unlike 1.6 and lower) you can use the following simplified procedure:

1. Install subversion 1.7 for your OS. If you are on osx and use homebrew, you can do it by running the following commands in terminal:

   brew tap homebrew/versions brew install subversion17

   Now, assuming you are in the root of your working copy:

2. Rename the .svn folder in your working copy (just in case you'll need to restore later):

   mv .svn .svn18

3. Do a new checkout in a temporary folder using subversion 1.7:

   svn co http://myrepo.com/ /tmp/v17

4. Copy only the .svn folder created by subversion 1.7 to your working copy:

   cp /tmp/v17/.svn .

If I read this correctly, there is no way to revert back. http://tortoisesvn.net/tsvn_1.8_releasenotes.html#compatibility (According to TortoiseSVN)
