# Desc: Upgrading from subversion 1.4 to 1.6.6 on CentOS 5
#       NOTE:These instructions are actually fairly generic 
#       in regards to the version of SVN you are upgrading
#       from/to. At the time of writing, it just happened
#       to be 1.4 -> 1.6.6

# Backup each repository
svnadmin dump /srv/svn/<repo> > /backup/svn/<Repo>_20091201_rXXXX.dump

# Backup any hooks or configuration files in 
# /srv/svn/<repo>/hooks and /srv/svn/conf

# Setup yum to allow the package to come in from
# RPMforge (must setup RPMforge repo first).
vim /etc/yum.repos.d/Centos-Base.repo

# Add the following line at the end of each section
# in the Centos-Base.repo
exclude=subversion mod_dav_svn

# Restart the yum update daemon
service yum-updatesd restart

# Upgrade subversion
yum upgrade subversion

# For each repository
#    delete the existing repo
rm -rf /srv/svn/<repo>

# Create a new repo
svnadmin create /srv/svn/<repo> --fs-type fsfs

# Import the data
svnadmin load /srv/svn/<repo> < /backup/srv/<Repo>_20091201_rXXXX.dump

# Restore any hooks or configuration files in 
# /srv/svn/<repo>/hooks and /srv/svn/<repo>/conf

# If you are using Trac, you'll need to resync the repo
trac-admin /srv/trac/<repo> resync
