OK I decided to write this up after unsuccessfully being able to find all the required info I needed in one place. In this setup we will be using Ubuntu Server 22.04.2 LTS as the OS. I have this running on a home lab ESXi server 8, on a HP Compaq Pro 6300 SFF CPU = Intel Core i7-3770 Installed Memory 16 GB I have some 10K SAS drives installed for the VM's If you have not already, navigate to  Get Ubuntu Server | Download | Ubuntu and download the 22.04.2 LTS ISO Next Lets create our VM that we are going to run this in. *Note Im using ESXi however you can probably do this in Workstation, Fusion, VirtualBox etc The main things to note on the VM creation. Set Ubuntu 64 bit as the guest OS Set your CPU relevant to the physicals CPU, I will be starting with 4 VCPU Set your Memory to as much as you can tolerate, I will be using 12 Disk Space - we are creating a 100G swap file, and the rest of the file can take up some room , so more is better if you can afford it Dont forget to add the U...

Upgrading View 5.3.5 + to View 6.x

-
One thing to keep in mind when upgrading is that View 5.3.5 disables SSLv3 and TLS 1.0. If you upgrade to View 6.x you will need to View 6.2.0 or 6.2, if you upgrade to 6.0 -6.1.1 you will be missing certain java components that have changed. Looks like it is in the release notes: http://pubs.vmware.com/Release_Notes/en/horizon-view/horizon-view-535-release-notes.html Upgrading View 5.3.5 to View 6.0 is not supported due to JRE incompatibilities. Workaround: Upgrade to View 6.1.0 or later

In-place Upgrading your 5.X ESXIi host to 6.X with Realtek drivers

-
Ok so after what should have been a simple 20 minute upgrade took 3 hours I'm writing the steps on how to upgrade your ESXi 5.X server to 6.0 in place and using the Realtek drivers If you only have Realtek NIC's you are going to need to firm make sure you have a FAT16 USB stick that will work in your host.  first get to a command line and run the following /etc/init.d/usbarbitrator stop Now insert your USB drive and run this command esxcli storage core device list | grep -i usb You should see something like  "Local USB Direct-Access" now run  ls /vmfs/volumes You should see a volume with  'NO NAME ' as the title (if you do not, then your USB drive is probably not supported or not formatted with FAT 16. format the drive with FAT 16 or try a different USB drive till you get one that works) Now that you have verified you have a Drive you can use on the host lets begin the upgrade. First download the NIC VIB from here  https://vibsdepot.v-front.de/wiki...

View 6.2.1 Upgrade

-
So One thing to keep in mind is if you are doing a staged upgrade of View, you may run into some issues with older versions of the client, or older versions of the agent. One thing that came up in my testing is if you are using PSG, and upgrade your servers first, you will not be able to connect. This has to do with the fact that TLS 1.0 is completely disabled by default. To fix this you must either enable it or upgrade your agents sooner. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2130798 It looks like they updated the documentation to show this. https://pubs.vmware.com/Release_Notes/en/horizon-6-view/horizon-621-view-release-notes.html

VMware View and vsphere 5.5U3b cause composer issues

-
So one thing I wanted to make people aware of is that if you upgrade your host to 5.5U3b, you will break VMware View on version older than 6.2. So why does this happen? With the release of 5.5U3b VMware has disabled SSLv3 http://pubs.vmware.com/Release_Notes/en/vsphere/55/vsphere-esxi-55u3b-release-notes.html Older version of View utilize the SSLv3 to communicate with both vCenter and the ESXi hosts. You may see errors such as: | UFA main thread 16 | FATAL | CommonLib.UfaSubsystem.UfaWorkItem - UFA error: fail in open computer operation. | UFA main thread 16 | INFO | CommonLib.UfaSubsystem.InitializeDiskUfaWorkItem - UFA error: fail to finish init disk operation for disk: datastore: [datastore_name] VMNAME1/VMNAME1-internal.vmdk, host: FQDN, port: 902. | UFA main thread 16 | FATAL | CommonLib.UfaSubsystem.InitializeDiskSetUfaWorkItem - Error: CompletionCallbackProxy failed to init disk with result If you have upgraded your host , you have 2 options. 1.
