How To: Upgrading

Upgrading from older versions of Omeka

1) Make a backup of your database in case something goes wrong during the upgrade (highly unlikely, but just to be safe).

2) Move your Omeka installation to somewhere else on your server.

3) Download and unzip your copy of the latest version of Omeka into the empty spot where your previous Omeka used to be.

4) Copy the following files and directories from your old Omeka folder to the corresponding location in your new Omeka installation:

• application/config/db.ini
• archive/files
• archive/thumbnails
• archive/square_thumbnails
• archive/fullsize
• any other files you have personally modified (be careful with this, as the original file may have been changed in newer versions).

5) Modify the permissions on your archive/ folder to make all folders and files within that directory writeable by your Apache web server.

6) Load Omeka in your web browser. The structure of your database will be modified automatically, so you will see a screen that says something like "Omeka is now upgrading itself." When that is done, reload the page and you will be done!
