Hi,

Testing a roll back procedure to a failed upgrade, I came up with this:

1. Before starting upgrade from 5.0.7 to 5.0.10 backup /opt/zimbra. I use cpio to copy the content of /opt/zimbra to /opt/zimbra.backup

# cd /opt/zimbra
# find . -print | cpio -pmudv /opt/zimbra.backup

2. Perform upgrade to 5.0.10 and follow the prompts.

# cd /var/tmp/zcs-NETWORK-5.0.10_GA_2638.RHEL4_64.20081003025447
# ./install.sh -x

3. Once upgrade is finished verify the new version.

$ zmcontrol -s

Release 5.0.10_GA_2638.RHEL4_64_20081003025447 RHEL4_64 NETWORK edition

$ rpm -qa | grep -i zimbra

zimbra-core-5.0.10_GA_2638.RHEL4_64-20081003025447
zimbra-spell-5.0.10_GA_2638.RHEL4_64-20081003025447

4. If upgrade failed, start rollback. Stop Zimbra

$ zmcontrol stop

5. Restore files from backup

# cd /opt/zimbra.backup
# find . -print | cpio -pmudv /opt/zimbra

6. Update RPM database only with previous packages. If you don't perform this step 'zmcontrol -v' will report version 5.0.10 as it gets this information from the RPM database.

# cd /var/tmp/zcs-NETWORK-5.0.7_GA_2450.RHEL4_64.20080630182541/packages
rpm -U --justdb --oldpackage zimbra-core-5.0.7_GA_2450.RHEL4_64-20080630182541.x86_64.rpm
