I am working on converting eight CVS repositories to Subversion. The CVS repositories are managed by CVS(nt) on Windows Server 2016, migrated there 2 months ago from a Windows Server 2003.
The new version control server is also running VisualSVN with Subversion 1.9.7. To do the conversion I am using cvs2svn version 2.5.0 on an Ubuntu 16.04.3 LTS Server. Python on the Ubuntu machine is the 2.7.12 version. Prior to conversion I have committed all of the uncommitted changes I have done myself and I have requested the developers to also commit all of their changes. The procedure I used to convert each repository is this: - Copy the repository files to a migration folder - Remove projects not needed in the conversion - Remove all CVS subdirectories in the repository (otherwise errors) - Remove all top level files so only subdirectories remain - Create a zipfile for the repository folder using 7zip - Copy the repository zipfiile to the Ubuntu 16 server - Expand the zip on Ubuntu into a migration folder - Run cvs2svn using an options file to create all projects as subrepositories in the main target repository - gzip the resulting dump file - Copy the dump file back to the Windows 2016 server - Use the VisualSVN management console to import the dump file to a new repository All of this worked without any visible problems. But it took quite some time to do... Now I wonder what will happen if some developer commits changes to the old CVS server.... Is it possible to update a Subversion repository with the new data somehow? (Except by manually copying the files to a svn working copy and committing from that). I would like to do this server side. I could use robocopy on the CVS repository to extract files that have changed after I made the migration into a folder structure that exactly mirrors the repo structure. If I use cvs2svn on these changed files (probably a small number of files) can then the resulting dump file be used to "mirror" the new commits in CVS to the Subversion version? Or is there some other way? -- Bo Berglund Developer in Sweden
