Today VMware Horizon 6.1.1 was released. The upgrade procedure is described in length at https://pubs.vmware.com/horizon-61-view/index.jsp#com.vmware.horizon-view.upgrade.doc/GUID-CE9531F4-6E70-494B-BE42-EF4666719F24.html
Important is that you must complete the upgrade process in a specific order.
Below a summary of the steps to take to upgrade your Horizon View environment to 6.1.1
- Stop/halt all View scheduled tasks
- Disable provisioning of all linked-clone desktop pools
- Edit Desktop/pools settings: set “Refresh OS disk on logoff” to never
- Upgrade View composer server
- Upgrade View Connection Server
- Upgrade View Security Server
- Specify a security server pairing password on the Connection server that will be paired with the security server you are upgrading
- Select “prepare for upgrade of reinstallation” to remove the existing IPsec rules
- Upgrade GPOs
- Upgrade View Agent on parent virtual machines
- Edit Desktop/pools settings: set “Refresh OS disk on logoff” to “Refresh immediately” (or whatever setting you had before)
- Enable provisioning of all linked-clone desktop pools
- Recompose linked clone Pools
- Upgrade View Clients
The upgrade is fairly simple and does not take too much time. I upgraded my demo environment which consists of 1 composer server, 2 connection servers, 1 security server and 1 rdsh host within 1 hour.
