This instructions are for MySQL users only. If you use another DB. Please

edit the queries in the queries/upgrade/ folder for your database

engine' s sytax and follow the same instructions.

Upgrading From 2.0.0

======================

No changes were made to the structure of the database.

You will want to backup all of your existing files and then replace them with the files from the current distribution.

You will need to reconfigure the includes/global.inc file.

Upgrading From 1.1.3

====================
No changes were made to the structure of the database.  The only new thing as far as the database goes is that passwords are no longer required to be stored in the database.  It is recommended that you execute queries similar to the following.

   Update tblUsers set password = "" where password != "";

   Update tblLoggedUsers set password = "" where password != "";

You will then want to backup all of your existing files and then replace them with the files from the current distribution.

The last thing to do is to reconfigure the includes/global.inc file.

Upgrading From 1.0.x

====================

Postaci 1.0.x series were not designed to multidatabase compatible. It was just a POP3 compliant webmail client and stored the e-mail in a MySQL database. 1.1.x series are completely different in design so it is almost impossible to upgrade to 1.1.x without loosing some data. Sorry, you have to install latest version because 1.0.x series will no longrer maintained.
