Today I upgraded the Subversion on my computer from 1.6 to 1.7 version. Subversion version 1.7 has a new repository structure and requires to upgrade all existing working copies.
If we attempt to use Subversion 1.7 on a working copy created with an older version of Subversion, then we will see the following error:
svn: E155036: Please see the 'svn upgrade' command svn: E155036: Working copy '/home/user/project' is too old (format 10, created by Subversion 1.6)
We need to use the
svn upgrade command to upgrade the working copy to the most recent metadata format supported by the new version of Subversion.
svn upgrade [PATH TO PROJECT]
Upgraded '.' Upgraded 'A' Upgraded 'A/B' Upgraded 'A/B/E'
Now my working copy is upgraded!
svn upgrade command need to do for every SVN working copy.
Note: After upgrading to Subversion 1.7, you cannot go back to Subversion 1.6. And upgraded working copies will be unusable by older versions of Subversion.
svn upgrade command may take a while, and for some users, it may be more practical to simply checkout a new working copy.
