RE: Dump from new and load to old

If I understand correctly, a repository created in 1.4 contains a different repository format. Since this format is different than the pre-1.4 format, you cannot load it in older versions. This seems to apply to both the WC and the entire repository.

Someone please correct me if I am wrong.

From the Release notes of 1.4:

http://subversion.tigris.org/svn_1.4_releasenotes.html

Working Copy and Repository Format Changes
Due to certain improvements and bugfixes made to the working copy library, the version number of the working copy format has been incremented. This means that Subversion clients earlier than 1.4 will not be able to work with working copies produced by Subversion 1.4. Similarly, the repository format has changed as well, meaning that pre-1.4 Subversion tools that normally access a repository directly (e.g. svnserve, mod_dav_svn, svnadmin) won't be able to read a repository originally created by Subversion 1.4.

WARNING: if a Subversion 1.4 client encounters a pre-1.4 working copy, it will automatically upgrade the working copy format as soon as it touches it, making it unreadable by older Subversion clients. If you are using several versions of Subversion on your machine, you need to be careful about which version you use in which working copy, to avoid accidentally upgrading the working copy format. This "auto upgrade" feature, however, does not occur with the new repository format.

Thanks,

Joe

Hi,

A friend of mine needs to dump a repo created with svn 1.4 and load it into a new repo created with svn 1.3.2 (an older version). For some reason, the load fails. I think it should be possible to do that load, but he argues that it's only possible to migrate a repo from and old version to a new one, and not the contrary. Is that true?

Cheers,

CÚlio.
