Upgrade Instructions

Below are the needed steps to upgrade you current Nucleus version to Nucleus v3.51.

Step 1: Create Backup

Creating a backup of your database contents and config.php file is always a good idea! In a normal situation, upgrading Nucleus won't corrupt your database at all, but you never can be sure enough.

Step 2: Upgrade Scripts

Download the file upgrade3.51-scripts.zip. It contains an upgrades/ directory which you should upload to your nucleus/ directory. You should overwrite the existing directory with the same name (or even better is to first delete the old one).

Now open your browser and go to the following url:

http://www.yoursite.com/nucleus/upgrades/index.php

You should see a list of needed upgrades which you still need to perform. Execute all of these upgrades. These should prepare your database for the upgrade.

To avoid security risks, you should delete the upgrades/ folder on your server after you've executed the scripts.

Step 3: Update Files

Download the file upgrade3.51-files.zip. The contents of this file shoud be uploaded on top of what's on your server. Files like config.php are not included here, so you don't need to worry about not overwriting that.

If you have been modifying files (e.g. css files), you might want to be a little more careful about which files you upload.

Step 4: Download an updated language file

If you are using a non-english language file, you should check if there's an updated language file available for download. When running Nucleus v3.51 with older language files, you'll see strings like _OVERVIEW_MANAGE in the admin area.

All Done!

It should work now... Thumbs up!
