Chapter 11. Upgrade Installation

If you have a previously installed version of PostNuke, or if you were running PHPNuke or MyPHPNuke, and wish to switch to PostNuke, you can use the Upgrade features of the installation to migrate your older system into the new PostNuke system.

Previous versions of PostNuke (versions 0.50, 0.60, 0.62, 0.63, 0.64, and 0.7x) can be automatically upgraded to the latest version of PostNuke using the upgrade function. Additionally, upgrades from MyPHPNuke (versions 1.87 and 1.88) and PHPNuke (versions 4.40, 5.20, 5.30, 5.31, and 5.40) to the latest version of PostNuke are supported by the upgrade process. Upgrades from PHPNuke 5.5 and later will be available in a future PostNuke release.

Through the upgrade process, user accounts are preserved, as are the settings for Articles, Blocks, Comments, Downloads, Headlines, and Reviews. Features that are specific to other CMS software (for example, article ratings in PHPNuke) are not converted and will be removed from the PostNuke database. Some modules and blocks may need to be upgraded to newer versions before they will function with PostNuke.

Click "Continue" to move to the next step.

You are presented a review of the database configuration selections that you just made. If they are incorrect, click "Change Info" to modify the selections. If the settings are correct, select "Upgrade" to upgrade from a previous version of PostNuke, or if you are migrating from PHPNuke or MyPHPNuke.

The next screen is where you select the CMS from which you are upgrading.

Click "Go to your PostNuke site" to enter your PostNuke site for the first time. Skip down to "Testing The Installation/Upgrade", below.

Once the upgrade has been tested to work, you may begin to migrate your NON-PostNuke files from the backup directory back into the web directory. You may now delete your previous-version backup files (for example, from /var/nukebackup)
