VCenter appliance 6.5 U1 has been released and which gives me the opportunity to update my lab's. Update process is really simple with the Appliance Management Tool. If your Appliance Server has connected to the Internet and can get packages over the internet, it will be easier then you imagine.
But at this step, we will explain the scenario that your Appliance Server has no communication with the Internet.
Step 1: Connect your Appliance Management Tool

Step 2: Login with Root Account
Step 3: Check Update status under the Update tab.
The first screenshot shows if you download the Zip file and start the update with Zip binaries. Second one shows if you directly connected to the internet and want to use the Vmware repository for the upgrade. The second option needs an internet connection.
At the first option, you need to download binaries at the VMware site. If you will continue with the second option then you don't need to download any packages. Just click the "Check for Update" button and wait until the package download finish.
Step 4: Download Binaries
Check for this link to download Zip file.
Step 5: Unzip files under WEB server root directory
As we explained before you need to create a repository server that your appliance management can access. So extract all binaries under the root directory of the webserver and check if you can get binaries over HTTP or HTTPS.
Step 6: Define your repository
Click the "Settings" button and define your repository URL.
Step 7: Check Update
Click Check update button then use the repository. Wait for Job then start to install updates. It will reboot Appliance then you finished.
