Question

Is it possible to port over comments from one project to a new Repository structure? Meaning is there some sort of comment file you can port?

Answer 1

You can migrate all repository data, including log messages and revision data, using the svnadmin dump and svnadmin load commands. The --parent-dir option will help you control where in the new repository structure all that data is imported.

For example if you currently have a repository for Project1, and you want to import all that data into MyCompanyRepository/Project1/trunk,

# On the repository server...
svnadmin dump /path/to/repo/for/Project1 > dumpfile
svnadmin load /path/to/repo/for/MyCompanyRepository --parent-dir Project1/trunk < dumpfile

See the Subversion book for details.
