# Upgrading TIBCO MFT Platform Server

When upgrading the TIBCO MFT Platform Server installation from an earlier version, you can run the install script and the output is similar with the regular installation.

## Procedure

1. On the command line, navigate to the $CFROOT directory.
2. Run the install script by using the following command.
   `./install`
3. Type `Y` to reinstall TIBCO MFT Platform Server for UNIX .
   If you type `N` or `n` here, the installer prompts you to remove the directory where you want to install TIBCO MFT Platform Server for UNIX first and try the installation again.
4. Type `Y` or `y` to keep your old configuration files.
   If you type `N` or `n`, your old configuration files are backed up and placed in a folder called $CFROOT/BACKUP_CONFIG.
   The installation proceeds as the regular installation after this step. For more information, see Installing with Root User and Installing with Non-Root User.
   Note: TIBCO MFT Platform Server versions prior to V8.0.1 installed the executables in the $CFROOT directory. V8.0.1 installs the executables in the $CFROOT/bin directory.
