Question :

Is there a way to use single Update manager (VUM), installed on Windows for multiple vCenter ? Version 6.5

One Update Manager must be associated (registered) with a single vCenter Server instance as per the documentation

VMware vSphere 6.5 Documentation Library-Understanding Update Manager

Thanks for the link.

I had already read the vmware docs. I wanted to know if, its possible or someone has already done it.

It will be a nice feature if it was available , but unfortunately current VUM releases does not support this.

VUM and vCenter is a one to one mapping as per the VUM documentation:

VMware vSphere Documentation

Hi,

Basically VUM and VC is one to one mapping. However, you can add multiple vCenter to vum from Update manager utility but that is not supported by VMware.

VUM has a utility called VMwareUpdateManagerUtility.exe in which we can re-register the vCenter Server . For ex we can install the VUM plugin to the first VCSA 1.1.1.1 and  update the ESX host. Later we can re-configure the VUM by running the utility and it will ask for the option to give the VC name or IP in which we can provide the second VC IP address.

Hope that answer your query.
