Something you might not be aware of is that most of the vCenter Server 6.5 services no longer register with the Windows Service Control Manager.
If you install or upgrade to a Windows vCenter Server 6.5 you will only see a handful of services when you launch services.msc.
No need to panic or think that the install didn’t go successfully.

Word of warning: When you get to vSphere 6.5, your vCenter Servers are stuck to whatever PSC Site they are currently located in!

This post should hopefully help you understand what is and what is not protected by VCHA and also what to expect depending on the situation.

There are a few gotcha’s and known issues that I have found with vCenter HA. Hopefully the following will be of use and avoid the need to engage VMware Support to resolve.
For more on VCHA please see my previous post which also includes short videos of both deployment methods.

One of the most anticipated features of vSphere 6.5 is native high availability for vCenter Server. No additional product like vCenter Server Heartbeat or no third party feature like MSCS/WFCS is needed.
The first thing to point out is that this feature is exclusive for the vCenter Server Appliance 6.5.
Windows vCenter Server 6.5 will still support MSCS/WFCS to provide high availability.

The vCenter Server Appliance has come a long way from it’s first iteration way back with vSphere 5.0. A moment of silence for the VCSA 5.0 with embedded DB2 database.
With the vSphere 6.5 release, the vCenter Server Appliance not only gains 100% parity with it’s Windows counterpart, but actually now exceeds it with some exclusive features.
You can interpret the fact that the VCSA is now getting exclusive features however you want to.
Please don’t ask me “Is the Windows vCenter going away?” – because I honestly don’t know the answer.

If a migration fails or you wish to roll back a successful migration then the basic steps are as follows:
1 Shutdown the Appliance 6.0 that has resulted from the migration
2 Power on the original source Windows 5.5 machine
3. The Windows machine will have lost it’s trust with the Active Directory Domain so you may need to log into the Windows machine as a local Administrator and re-join the Active Directory Domain and reboot the Windows machine.
Note: This is because the resulting vCenter Server Appliance 6.0 will have overwritten the Windows vCenter computer account on the AD.
Important: If you have other solutions that have been upgrade for compatibility with vSphere 6.0 these may cease to work after the rollback and would need to be rolled back themselves. This includes ESXi 6.0 as this is not manageable from a vCenter Server 5.5. Also be careful that you do not have Virtual Machines running Hardware Version 11 as these VMs cannot run on ESXi 5.5 or older.
I’ll go into a little more detail on different typologies as the larger and more distributed the environment the more caution and planning is needed
