Moving SVN Repositories

I recently relocated a number SVN repositories to a new hosting provider. To do so I ended up merging ideas from a number of different locations, so here is a quicknote that summarizes the various steps, both for the server & working copies:

 Moving the Repository

On old host:

  1. Dump the entire repository to a file using: svnadmin dump /path/to/repository > repo-name.dmp [1]. Take care, dump outputs to standard output, to avoid seeing lots of gibberish, be sure to redirect the output to a file (using >)
  2. Zip this file to save space (it typically compresses well) using zip repo.zip repo-name.dmp
  3. Rename the old repository to prevent accidentally using it using:

    mv /path/to/repository /path/to/repository-old

On new host:

  1. Transfer the zipped dump file to the new host. This can be done using

    [new_host]$ cd svn_repos_folder
    [new_host]$ sftp user@old.host.com
    stfp> cd path/to/repository
    sftp> get repo.zip
    sftp> exit

  2. Create a new empty repository using svnadmin create repo-name [1]

  3. Extract the dump file using unzip repo.zip

  4. Import the old repository using svnadmin load repository-name --force-uuid < repo-name.dmp [1]. At this point the new repository should be ready to use, with the complete history from the old repository

Updating Working copies

  1. Run svn switch --relocate http://my.original.repository.com/proj1/trunk http://my.new.repository.com/proj1/trunk [2] to convert all old links within the working copy to the new location.

Hint: you can get the old repository URL using svn info

Additional notes for Versions (Mac OSX Subversion client, tested with v1.2.2)

  • Repositories links can be updated by right clicking and selecting “Edit Bookmark.”
  • Working copies are not automatically updated, use the command line instructions above.
  • Verify that the changes are working by exploring the timeline

One Response to Moving SVN Repositories

  1. You can also use svnsync to move the repository; that way you can transfer all the data without the need to take the ‘old’ repository down. This is also the only way I know of to get your data from hosted environments, where you don’t have shell access or access to dumping the repository.

To create code blocks or other preformatted text, indent by four spaces:

To create not a block, but an inline code span, use backticks:

Here is some inline `code`.
