Install/Admin SVN

Migrating from CVS to SVN

cvs2svn --dumpfile path/to/dumpfile /path/to/cvsrepo

svnadmin create /path/to/svnrepo svnadmin load /path/to/svnrepo < cvs2svn-dump

Convert existing SVN repository from Berkeley DB to FSFS

Create dump files from existing svn directories.

for i in *; do svnadmin dump $i > $i.dump; done

Create tar file to transfer to new host.

tar cfvz svn.tar.gz *.dump

Transfer and extract somewhere, then we create new repos of fsfs type for each dumpfile.

for i in *.dump; do svnadmin create ${i%%.*} --fs-type fsfs ; done

Load the dump file into the newly created repo.

for i in *.dump; do cat $i | svnadmin load ${i%%.*} ; done
