| This article applies to the following ZCS versions. |
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. Check your database integrity
http://wiki.zimbra.com/wiki/Zmdbintegrityreport
/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
https://wiki.zimbra.com/wiki/CLI_-_zmbackup_Network_Edition_Only
Note: this may take multiple hours, be sure to plan in advance:
zmbackup -f
b. Backup your LDAP data
http://wiki.zimbra.com/wiki/LDAP_data_import_export
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
