<h2>Migration Information</h2>
<p>Current (legacy) NVIDA license service reaches end of support on July 31st, 2023. Therefore a new NVIDIA license service was prepared. The new NVIDIA license service is based on DLS version 3.1 (Delegated License Service 3.1 - <a href="https://docs.nvidia.com/license-system/dls/3.1.0/index.html">https://docs.nvidia.com/license-system/dls/3.1.0/index.html</a>).</p>
<p>The new NVIDA license service uses the same DNS names and IPs, but different port (443) and requires new client configuration with a token file.</p>
<p><strong>All existing Windows GPU instances require new client configuration or reinstallation.</strong> All public Windows GPU images from public Image Management Service already uses the new NVIDIA license service.</p>
<p>Linux GPU instances created from our public images are not effected, as unlicensed NVIDIA open source driver is used.</p>
<p><strong>DNS change in eu-nl to new IPs and new license server is scheduled for 4. March 2024. Old license server is only reachable via old IPs afterwards</strong></p>
<p><strong>Run down of all old license servers is scheduled for 11. March 2024.</strong></p>

<h3>How to check connection to new NVIDIA license servers</h3>
<p>start PowerShell and run commands:</p>
<pre><code>Test-NetConnection gpulicence01.eu-de.otc-service.com -port 443
Test-NetConnection gpulicence02.eu-de.otc-service.com -port 443
Test-NetConnection 198.19.34.77 -port 443
Test-NetConnection 198.19.44.221 -port 443 </code></pre>
<p>test result should be: </p>
<pre><code>TcpTestSucceeded : True</code></pre>
<p>example:</p>
<pre><code>PS C:\Users\Administrator\Desktop> Test-NetConnection gpulicence01.eu-de.otc-service.com -port 443
ComputerName : gpulicence01.eu-de.otc-service.com

<h3>How to reconfigure NVIDIA license server client on Windows Servers</h3>
<h4>Reconfiguration with Chocolatey (eu-de only)</h4>
<ul>
<li>Install Chocolatey client if not already done</li>
</ul>
<pre><code># define chocolatey server - choose the right one for your region
$ChocoServer = 'chocolatey.eu-de.otc-service.com'
# $ChocoServer = 'chocolatey.eu-nl.otc-service.com'
# download and install the client
Set-ExecutionPolicy Bypass -Scope Process -Force
iex ((New-Object System.Net.WebClient).DownloadString("http://$ChocoServer/install.ps1"))</code></pre>
<ul>
<li>Install Chocolatey Package OTCnvidialicense (set ChocoServer with server of region and choose install, upgrade or upgrade all command)</li>
</ul>
<pre><code># define chocolatey server - choose the right one for your region
$ChocoServer = 'chocolatey.eu-de.otc-service.com'
# $ChocoServer = 'chocolatey.eu-nl.otc-service.com'
# install chocolatey package
choco install OTCnvidialicense --source="http://$ChocoServer/chocolatey"
# force reinstallation chocolatey package and confirm all messages automatically
choco install OTCnvidialicense -y --force --source="http://$ChocoServer/chocolatey"
# upgrade specific chocolatey package (if already installed)
choco upgrade OTCnvidialicense -y --source="http://$ChocoServer/chocolatey"
# upgrade all chocolatey packages
choco upgrade all -y --source="http://$ChocoServer/chocolatey"</code></pre>
<h4>Manual Reconfiguration</h4>
<ul>
<li>
<p>Download NVIDIA client token file (eu-de):
