Vsphere 6 Upgrade Path and Options.

vsphere6v6install1`

 

Before you begin, make sure that you read the vSphere 6 upgrade guide, the vSphere 6 release notes, the Hardware and Guest OS Compatibility Guide and the Product Interoperability Matrix from VMware before you start the upgrade process. Also, make sure your environment meets the software and hardware requirements as described in the upgrade guide.

Since the vSphere 6 introduces the VMware Platform Services Controller, you should have a look at the vCenter Server upgrade path example as described in the upgrade guide to fully understand the changes in your environment after the upgrade for vSphere 6. For example: I am running a simple installation of the vCenter Server (Inventory Service, Web Client, Single Sign-On) on a Windows Server 2008 R2 virtual machine with Update Manager, Auto Deploy, Dump Collector, Syslog and a Microsoft SQL Server 2008 R2 Express. So according to the upgrade guide, my new vCenter Server infrastructure.

The upgrade of your environment to VMware vSphere 6.0 is performed in a phased manner. The components that are upgraded in earlier phases are fully compatible with components whose upgrades have not yet occurred. – See more at: http://www.vmware.com/products/vsphere/upgrade-center/upgrade.html#sthash.zcolKAMA.dpuf

    Planning for the Upgrade:If you are planning for an upgrade, the first thing you have to do is ensure that there is product interoperability with all the third party tools and plugins that you use everyday. If you are confident that its going to be OK, this is how to plan for it. Ensure you plan and test this on a non-production environment. Stress test the new environment with application VMs and other tests that you generally perform on a green fields environment. Write out your plan. My plan (for my lab is as below)Plan out your SSO deployment model and how to upgrade to the new PSC model. (Always deploy PSC in a HA mode with multiple VMs. It has inbuilt replication and so you don’t have to setup anything for it ).
    Snapshot your SSO Server and then Install the new PSC (Platform Services Console) and ensure that SSO and licensing of the existing environment is migrated over. Once everything works, don’t forget to delete that snapshot.
    Snapshot the vCenter Server (including the SQL Server and the vCenter DB) and upgrade the components of the Management Platform (vCenter, VUM etc). Delete Snapshot again.
    Ensure all the licensing is intact and that you can login with the required permissions. This is paramount to test this as you don’t want to upgrade and then realise that it needs newer permissions etc.
    Upgrade your hosts one by one using VUM update.
    Test out each of the new features that you want to use in your environment.
    Document everything I mean everything this way you can run through all the tests you’ve done and repeat any with less than satisfactory results.
    Test all the failed tests after all the components have been upgraded. If it still fails the test, if you have VMware Support for your non-production licenses then log a case with VMware Support.
    Once resolved, re-run your tests until all of them are successful.
