These instructions are for upgrading from OpenClinica 3.0.x to version 3.1 , 3.1.x maintenance release or to a 3.2 on Windows systems running the essential software dependencies: Java 6, Tomact 6, and PostgreSQL 8.4. When you see v.x or v.x.x or similar in the instructions, use the version number you are upgrading to, e.g. 3.1 or 3.1.2.
The instructions apply only if you followed the upgrade instructions to get to 3.0.x; if you did not, you might need to do other things in order to upgrade your system.
If you are running an earlier version of OpenClinica and/or its related software dependencies, make sure you upgrade these to the required versions before upgrading beyond OpenClinica 3.0.x. Please note that these instructions do not cover upgrading related software dependencies for 3.1.x. To upgrade these components, you'll need to follow the instructions provided by those technologies. Make sure you back up everything so your existing files are not lost.
If you are upgrading from OpenClnica 2.5.x, you need to first upgrade to 3.0.x, and you will need to upgrade the software dependencies so they meets the requirements for OpenClinica 3.0.x. Perform a full backup of your 2.5.x instance, perform a fresh install of 3.0.x, and then restore your 2.5.x data. For information about backing up your 2.5.x instance, see the 3.0.x upgrade documentation that is included with the downloaded files for 3.0.x.
