Downgrade a patch using Zypper

To downgrade a patch on your TeamForge site using the Zypper installer, you need to specify the version of the patch release to which you're downgrading.

1. Stop TeamForge.
   • /etc/init.d/apache2 stop
   • /etc/init.d/postgresql stop
   • /etc/init.d/collabnet stop
2. Run the downgrade command.

   For example, to downgrade from patch level 2 to patch level 1 of build #118 of TeamForge, here's the command:

   • zypper install teamforge-sles-6.1.1.1-118
   To downgrade from patch level 1 to patch level 0 of build #118, here's the command:
   • zypper install teamforge-sles-6.1.1.0-118
   Note: During the downgrade, the site-options.conf file is automatically backed up into /opt/collabnet/teamforge-installer//6.1.1.0/conf.
3. Recreate the runtime environment.
   • cd /opt/collabnet/teamforge-installer/6.1.1.0
   • ./install.sh -r -n -V -I -d /opt/collabnet/teamforge
4. Start TeamForge.
   • /etc/init.d/apache2 start
   • /etc/init.d/postgresql start
   • /etc/init.d/collabnet start
5. Verify that the patch was reverted.
   1. Log onto the site as a site administrator.
   2. On the Admin tab, click System Tools.
   3. Click Build Information and observe which patches are present.
