Before upgrading your Zimbra platform, we would strongly recommend the following pre-upgrade steps:

0. Prepare

Always read (in full) the Release Notes for the version to which you are upgrading. The Release Notes are available for every release:

http://www.zimbra.com/downloads/ne-downloads.html

1. Backup your system

There are multiple ways to perform backups. Since upgrading permanently alters your system, it is mandatory to backup your system before you upgrade. The only recovery from a failed upgrade may be to restore from backups:

a. zmbackup your entire system:

Note: this may take multiple hours, be sure to plan in advance:

zmbackup -f

b. Backup your LDAP data:

Main database:

/opt/zimbra/libexec/zmslapcat /var/tmp

Config database:

/opt/zimbra/libexec/zmslapcat -c /tmp

Accesslog database (on LDAP Master only):

/opt/zimbra/libexec/zmslapcat -a /tmp

$ zmsetvars

If using binary logging, the dump is run like the following:

$ /opt/zimbra/mysql/bin/mysqldump --user=root --password=$mysql_root_password --socket=$mysql_socket \
 --all-databases --single-transaction --master-data --flush-logs > {dump-file}.sql

If not using binary logging, the dump is run like the following:

$ /opt/zimbra/mysql/bin/mysqldump --user=root --password=$mysql_root_password --socket=$mysql_socket \
