This page explains how to upgrade to 1.9.0

Warning

• 1.9.0 is fresh and you can expect minor bugs. Please report on dev.tikiwiki.org/tracker5
  Any sane admin with a valuable Tiki will want to backup its database before the upgrade, using MySQL (for example mysqldump or phpMyAdmin).
  plus backup daily incase of problems.
• Upgrading will require a number of files. Leaving tiki-install.php or sql files after upgrading is a bad idea that could potentially help people to screw up your Tiki.

Upgrading from before 1.8

• Please see the UpgradeTo18 page, and follow the steps carefully

Upgrading from Version 1.8

1. Backup your existing database (use the command msqldump or use phpMyAdmin)
2. Download the 1.9 package from our SourceForge Project Area
3. Uncompress the 1.9 package
4. Upgrade your database (see below)
5. Copy over the contents of the 1.9 tiki dir to your exisiting tiki web root (eg /var/www/html/tiki)
   • Linux users can use: cp -R tiki/* /var/www/html/tiki/.
6. Run setup.sh again to verify the correct permissions are set
7. Remove the contents of templates_c, the temp and modules/cache directories

You should now be running a 1.9 site.

Upgrading the database

Upgrade scripts are located in the "db" subdirectory and are run with this mysql command: mysql -f -u dbuser -p tikidb < tiki_1.8to1.9.sql
where "dbuser" is the name of a mysql user with sufficient privs in the tiki db to modify that table structures and data rows (probably root), and "tikidb" is the name of your tiki database. The -p is only needed if you have a password on the database (which is highly recommended). The -f is required to force all the updates to occur. You can safely ignore any errors, but if the script aborts (as it would without the -f), then your database will be missing part of the update.
