Licensing Note

Check your license expiration

From Cerb2 or Cerb3

If you're still running Cerb2 or Cerb3 then the Cerb6 upgrade process is the same as the Cerb4/Cerb5 process. This is required because the 4.x/5.x/6.x database is in an entirely different format. Read the instructions on upgrading from 2.x/3.x to Cerb4/5. You will need to install Cerb6 first.

From Cerb4 / Cerb5

• The database is upgradeable (e.g. no tedious migration necessary).
• The filesystem is not upgradeable.
• The source code repositories (GitHub and Subversion) have moved.
• Make a backup!!

Download

• Download the Cerb6 files and install them in a new location.

Subversion

 svn co "https://github.com/wgm/cerb6.git/branches/stable" cerb6

GitHub

 git clone "http://github.com/wgm/cerb6.git" cerb6

Database

• Copy the following settings from /cerb5/framework.config.php to /cerb6/framework.config.php:

 APP_DB_DRIVER
 APP_DB_HOST
 APP_DB_DATABASE
 APP_DB_USER
 APP_DB_PASS'
 APP_DB_PCONNECT
 LANG_CHARSET_CODE
 DB_CHARSET_CODE

NOTE: If you haven't upgraded your Cerb4 database to UTF-8 yet, now would be a good time to do that.

Storage

• Move your custom plugins from /cerb4/plugins to /cerb6/storage/plugins (Move only any custom plugins you have developed. Do not move the default plugins.)
• Copy /cerb4/storage/attachments/* to /cerb6/storage/attachments (do not copy the hidden /storage/attachments/.svn directory)

You could use rsync to do this, since it has the nice -C option, which ignores any SVN or CVS files. (see man rsync)

For example:

[root@cerberus html]# rsync -aCv cerb4/storage/attachments/ cerb6/storage/attachments/

• You will want to clear you cache Clearing_the_cache as well

Permissions

• All the /cerb6 files should be readable by your webserver user.
• All the contents of the /cerb6/storage directory should be writeable by your webserver user.

Pretty URLs

• If you're running Apache with mod_rewrite enabled, simply copy the /cerb6/.htaccess-dist file to /cerb6/.htaccess and your helpdesk URLs should become prettier (i.e., /cerb6/index.php/tickets becomes /cerb6/tickets).

Upgrade

• Open http://www.example.com/cerb6/ in your web browser and the system will patch itself.

Security
