vRealize Operations 6.1 is now available, I thought I would put a quick guide together as I go through the upgrade process.

To upgrade from vRealize Operations Manager to the most recent version, follow these steps.

Download the PAK file(s) needed based on the type of cluster.

vApp clusters
The vApp cluster requires the deployment of the OS upgrade and the product upgrade .pak files.
For an OS upgrade, the file is: vRealize_Operations_Manager-VA-OS-xxx.pakFor the product upgrade of vApp clusters, the file is: vRealize_Operations_Manager-VA-xxx.pak
vApp heterogeneous clusters
The vApp heterogeneous cluster requires the deployment of the OS upgrade and the product upgrade .pak files.
For an OS upgrade, the file is: vRealize_Operations_Manager-VA-OS-xxx.pakFor the product upgrade of a heterogeneous cluster that has VA nodes with Windows Remote Collectors, the file is: vRealize_Operations_Manager-VA-WIN-xxx.pak
RHEL standalone clusters
The RHEL standalone cluster requires the deployment of only the product upgrade .pak file.For the product upgrade of RHEL clusters, the file is: vRealize_Operations_Manager-RHEL-xxx.pak
RHEL heterogeneous clusters
The RHEL heterogeneous cluster requires the deployment of only the product upgrade .pak file.For the product upgrade of a heterogeneous cluster that has RHEL nodes with Windows Remote Collectors, the file is: vRealize_Operations_Manager-RHEL-WIN-xxx.pak
Windows clusters
The Windows cluster requires the deployment of only the product upgrade .pak file.For the product upgrade of Windows clusters, the file is: vRealize_Operations_Manager-WIN-xxx.pak

The rest of the upgrade process is pretty straightforward.
