Installation : How do I upgrade to a new version of the EPS?
All of the EPS installers will upgrade any previous versions of the EPS. You should download and run the same installer as you originally used for your installation and follow the on-screen prompts.
If you are using the compressed installations which do not have an executable installer you can extract these to any location you wish. If you are using a previous version of the EPS you should ensure that your newly extracted installation includes any database drivers which were installed into your old installation. If you wish to re-use the same directory for your new installation you should delete all of the contents first, ensuring that you make a copy of any database drivers in order to copy them back into the new installation.
