Warnings

Please also see the following links if you want to upgrade to the latest stable version of TikiWiki from either 1.8.x or 1.9.x

• UpgradeTo193
• UpgradeTo192
• UpgradeTo191

Other warnings:

• 1.9.0 does contain security issues, you are advised to upgrade straight to release 1.9.2, at least, or to the latest stable version (without installing 1.9.0)
• As with any new stable version, you can expect minor bugs with 1.9.x branch. Please report them on http://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 in case 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. Clear templates and module cache in Admin -> System Admin
2. Backup your existing database (use the command mysqldump or use phpMyAdmin)
3. Download the 1.9.x package from our SourceForge Project Area
4. Uncompress the 1.9.x package
5. Upgrade your database (see below)
6. Copy over the contents of the 1.9.x tiki dir to your exisiting tiki web root (eg /var/www/html/tiki)
   • Linux users can use: cp -R tiki/* /var/www/html/tiki/.
   • Windows users equiv: xcopy tiki\* c:\inetpub\wwwroot\tiki\ /e
7. Run setup.sh again to verify the correct permissions are set
8. Remove the contents of templates_c, the temp and modules/cache directories

You should now be running a 1.9.x site.

Notes:

• Do not delete the 1.8.x directory and uncompress tiki 1.9.x over. You may loose images uploaded in wiki or custom avatars or some other content. If you want to have a clean install (no old files) then make a backup of the 1.8.x installation directory before you do that.
• You can use the secdb database files to check your installation directory for old/modified files. See AdminSecurity

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.

(Note: If you are upgrading to 1.9.y from a previous 1.9.x, you will also need to run the 1.9.xto1.9.y.sql script)

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.

The new classes that have been added from 1.8 to 1.9 are listed in the file styles/transitions/1.8to1.10.css
