Updating the hardware-based license server

To update the hardware-based license server, you need to return the exiting license first. Then, run the installer from the root user ID to update the hardware-based license server, and enable the license server again.

Before you update the hardware-based license server, you need to return the exiting license key. For the steps to update the hardware-based license server, see Returning a hardware-based license key.

To update the hardware-based license server, complete the following steps:

Open the directory that contains the installer ZDT_Install_PS_V14.0.0.tgz.
Change the authority.
```
chmod 755 ZDT_Install_PS_V14.0.0.tgz
```
Decompress the installer.
```
tar -xzvf ZDT_Install_PS_V14.0.0.tgz
```
Optional: Read the README.txt file for the complete installation steps.
Run the installer.
```
./ZDT_Install_PS_V14.0.0.x86_64
```
Select 3 for hardware-based license server.
Select 2 to update.
Press ENTER, and read the license agreements carefully. At the end of the license, enter yes to accept or no to decline the terms.
If the package is updated successfully, the following output is displayed.
```
z1091-1-10.55.12.x86_64
```

Alternatively, after you complete steps 1 - 4, you can update the hardware-based license server silently by using the following command.

./ZDT_Install_PS_V14.0.0.x86_64 --update --zdthwlicense

After the hardware-based license server is updated, you need to enable the license server by running the steps that are described in Enabling the license servers.
