This may not be the answer to your question, but there's not much benefit in what you're planning.
- vSphere 5.5 will be out of support in September
- vCenter Server 5.5 is not supported on Windows 2016, nor with SQL Server 2017
- vCenter Server for Windows will not be available anymore in future vSphere versions
If you are not ready yet to move to the vCSA, I'd suggest you either leave your current system running until you are ready, or - if this is not an option - convert it into a VM.
thank you for you advice. Shame on me, i never thought on such compatibility issues.
Unfortunately I can't virualize the machine right now because it a Contoller card for connection with a robotic library.
Anyway, when the backup is moved I think I'll virtualize the vCenter,
