Deprecating CVS and Subversion imports

What are code imports?

Launchpad’s code import service allows users to automatically mirror code from external version control systems into Launchpad. Historically, this has supported imports from CVS, Subversion, Bazaar and Git.

As part of this, Launchpad currently also supports imports into Bazaar branches from:

Concurrent Version System to Bazaar
Subversion via cvs2svn to Bazaar
Subversion via bzr-svn to Bazaar

These imports will be deprecated.

Why deprecate these imports?

As announced in Phasing out Bazaar code hosting, Bazaar itself has been deprecated and is no longer actively developed. The last release was in 2016, and usage has steadily declined.

Maintaining imports from these less common version controls to Bazaar requires significant efforts.

To streamline our services and focus resources where they matter most, Launchpad will be retiring the previously mentioned Bazaar-based imports.

Timelines

September 18th, 2025: No new import configurations for the previously mentioned Bazaar-based imports will be accepted.
October 1st, 2025: All existing CVS to Bazaar and SVN to Bazaar imports (both cvs2svn and bzr-svn) will be shut down. Import jobs will no longer run after this date.

Migration paths

If you are currently using these imports, we recommend:

Migrating the source repository to Git.
Reconfiguring your Launchpad project to use a Git-based import instead.

Guides and references:

Migrate a Repository From Bazaar to Git
General CVS/SVN to Git migration tools (such as git cvsimport, svn2git, or git svn) are widely documented.
