The purpose of this script is to migrate from one vCenter to another when using dvSwitches. The dvSwitch is bound to vCenter, so in order to migrate hosts from one vCenter to another you can map the networks using this script. All you need to do is disconnect the host from the original vCenter with the VMs still running, but not remove it. Then you connect it to the new vCenter.

Migrate Tags from one vCenter to another
When upgrading to vSphere 7 or any other version, you might choose to create a brand new vCenter instead of migrating the old one. But what about folder structure, tags, distributed switches and so on.
Here I will demonstrate how you can easily migrate your tags from one vCenter to another using VMware PowerCLI.

vRA 8.1 Custom Resources
Todays announcement of vRealize Automation 8.1 reveals the possibility to use Custom resources in vRA.
I am super exited about that ability. Those who know me, knows that I am a HUGE fan of vRO (vRealize Orchestrator) and the possibility to add anything as a resource in a vRA really opens the product to so many possibilities.
Anything you can imagine, and that you can make vRO do, you can put in a blueprint.
Spoiler alert. New vRA 8.1 feature
Applying automatic fix for PowershellScriptExecution prerequisite failed
When upgrading from vRealize Automation 7.4 to 7.5 or other versions you might get the error:
Applying automatic fix for PowershellScriptExecution prerequisite failed or Pre-install: failed (code p-1)
There can be many reasons for this, but in my case it was a GPO that prohibited PowerShell from executing scripts. as referenced here: VMware
For you it might be something else. Tto figure out what the error was you can start of by looking in the logs, but there is actually much more information available in the original output which gets parsed, and then deleted.
Please be aware that the following is quite technical, and it is not very likely that you can use the fix demonstrated here out of the box, but I might give you a hint or two on how to troubleshoot your own issue.

Migrate folder structure from old to new vSphere vCenter
Sometimes I find it easier to create a new vCenter server then migrate the old one, and it is a perfectly good solution in many cases.
But annoyingly there is a lot of manual work involved.
One problem is the VM’s and Templates folders. They do not follow the host, so you have to create the folder structure manually and move each VM into the correct folder. Well I am way to lazy to do that by hand, so it’s time to Automate! Continue reading Migrate folder structure from old to new vSphere vCenter
Assigning vCenter tags using vRealize Orchestrator
Today I needed to assign some vCenter tags to some VMs I was deploying using vRealize Automation.
The scenario was that the customer did not want backup of VMs deployed by the vRA test environment, and in production they wanted a specific backup tier.
They are using Veeam backup, so the vRA test environment needed to have a NoBackup Tag, and production needed some other tag, depending on the type of server being deployed.
vRO does not provide very extensive support for these operations out of the box, but vRO 7.2 does come with some sample workflows.
To get started with vCenter tagging you need to configure a vAPI endpoint and a vAPI metamodel.
