Use the following steps to upgrade to v4.0. These steps assume that you are familiar with PhpGedView and have successfully installed it before.

Version 4.0 no longer includes support for index files. If you do not have PHP 5 with built-in SQLite support or a database account then you should not upgrade to PhpGedView 4.0. Maintenance releases will continue for the 3.3.x version.

**Note to SQLite users: Unfortunately SQLite does not support the ALTER TABLE SQL command. This means that we must first drop the tables and recrate them. It is highly reccomended that you run the backup before upgrading.

1. Upload the new 4.0 files to your server replacing the old files with the new files. Do not replace the config.php file or the index directory.
2. Go to upgrade33-40.php in your browser.
3. In order to create the data required for the new version, you will have to re-import your GEDCOM. Please see the section on UPDATING GEDCOMS below.
4. You can now use your upgraded site. One change with this version splits user's full names into first and last name fields. If you have users who only entered a single name then their first and last name will be the same and it will appear doubled on some screens. You may want to review your user list and check your user's names.
5. If you are using a customized theme you will need to update your theme with new stylesheets and variables. An excellent tool that can help you to merge themes is the WinMerge project http://winmerge.sourceforge.net/

If you are upgrading from a version prior to v2.65 then you should start with a fresh install by
following the installation instructions.
