This section provides the steps required for a successful upgrade from Zabbix 1.8.x to 2.0.
Database upgrade to version 2.0 may take a long time, as all the historical data tables have to be upgraded.
Stop Zabbix server to make sure that no new data is inserted into database.
This is a very important step. Make sure that you have a backup of your database. It will help if the upgrade procedure fails (lack of disk space, power off, any unexpected problem).
Make a backup copy of Zabbix binaries, configuration files and PHP files.
You may use pre-compiled binaries or compile your own.
Some parameters of zabbix_server.conf might have changed from 1.8, new parameters added. You may want to review them.
Before you upgrade:
Database upgrade scripts are located in the upgrades/dbpatches/2.0/<db engine> directory. Run the scripts:
These scripts are only for upgrading Zabbix 1.8.x to 2.0! For upgrading from earlier versions first use upgrade scripts from Zabbix 1.6.x or Zabbix 1.8.x.
Follow installation instructions.
Start new binaries. Check log files to see if the binaries have started successfully.
