6 Upgrade procedure
Overview
This section provides the steps required for a successful upgrade from Áú»¢¶Ä²© 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.
Make sure to read upgrade notes before proceeding with the upgrade.
1 Stop Áú»¢¶Ä²© server
Stop Áú»¢¶Ä²© server to make sure that no new data is inserted into database.
2 Back up the existing Áú»¢¶Ä²© 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).
3 Back up configuration files, PHP files and Áú»¢¶Ä²© binaries
Make a backup copy of Áú»¢¶Ä²© binaries, configuration files and PHP files.
4 Install new server binaries
You may use pre-compiled binaries or compile your own.
5 Review server configuration parameters
Some parameters of zabbix_server.conf might have changed from 1.8, new parameters added. You may want to review them.
6 Upgrade the database
Before you upgrade:
- Make sure the database user has enough permissions (create table, drop table, create index, drop index)
- Make sure you have enough free disk space.
Database upgrade scripts are located in the upgrades/dbpatches/2.0/<db engine> directory. Run the scripts:
- MySQL: upgrades/dbpatches/2.0/mysql/patch.sql
- PostgreSQL: upgrades/dbpatches/2.0/postgresql/patch.sql
- Oracle: upgrades/dbpatches/2.0/oracle/patch.sql
- IBM DB2: upgrades/dbpatches/2.0/ibm_db2/patch.sql
These scripts are only for upgrading Áú»¢¶Ä²© 1.8.x to 2.0! For upgrading from earlier versions first use upgrade scripts from Áú»¢¶Ä²© 1.6.x or Áú»¢¶Ä²© 1.8.x.
7 Install new Áú»¢¶Ä²© web interface
Follow installation instructions.
8 Start new Áú»¢¶Ä²© binaries
Start new binaries. Check log files to see if the binaries have started successfully.
