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:

1. Check your database integrity

/opt/zimbra/libexec/zmdbintegrityreport -v

2. 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

c. Backup your MySQL data

# su - zimbra
$ source ~/bin/zmshutil
$ 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 \
 --all-databases --single-transaction --flush-logs > {dump-file}.sql
