You can now use the in-place upgrade method to upgrade your server to the newer version. The in-place upgrade method upgrades the server to the same directory on your computer where the server was originally installed. This method does not require you to install a new instance of the server or database and migrate artifacts, global variables, and history data.
Note: The in-place upgrade method is applicable only for upgrading the server from r11.3 or higher.

Hope this helps!
Please, I would like to know if it is possible to use the method “Upgrade the Server Using Migration Method” when the target database is different from the original? For example : Source is ORACLE and target database will be SQL SERVER ?
When you are doing an in-place upgrade of DE from 11.3 to R12, the target DB cannot be changed. The whole idea of in-place upgrade is to allow current setup to be upgraded, without changing current DE host and DB.
If you want to use a separate DB then you may want to look in to the migration feature of DE.
