   Great article, I just used it to migrate from svn 1.1 on an old server to 1.7 on a new one. Everything seems good.

   In response to other comments, one way to deal with large dumps is to transfer them directly over the network. This is what I did:

   Create the repo on the new server:

   me@newserver$ svnadmin create /path/to/new/repo

   And then transfer from the old to the new with ssh:

   me@oldserver$ svnadmin dump /path/to/old/repo | ssh me@newserver sudo svnadmin load /path/to/new/repo

   This puts the output of the dump (on the old server) to standard output, which is then piped to the ssh command, which is then directed to standard input of the load command.

   Hi,

   I have a large dump file (100 GB), what is a best way to filter out / decrease the size. AFAIK removing old revisions isnt a safe way.

   Please guide.

   Thanks,

   Since the dump is only a single file, you do not need tar.
   You could even add the gzip compression to the dump command:

   svnadmin dump /path/to/your/repo | gzip -c > yourreporname.dump.gz

   And load it to the new server with:

   gzip -cd yourreporname.dump.gz | svnadmin load reponame

   Or use bzip2 instead of gzip; slower, but better compression. May be an issue when transfering the large file to the new machine.

    small typo:
    scp yourreponame.dump username:new.machine.ip:/path/to/your/new/repo
    should be:
    scp yourreponame.dump username@new.machine.ip:/path/to/your/new/repo
