Virtualisation and Digi

we use Accele Port 16p for many years and have no comlaints about its performance or stability.
But as the time goes by, we need to virtualise our environment.
Taking this into account, obviously, existing serial infrastructure won’t work in any available virtual environments (Microsoft or VMware or any other).
What can you suggest? How should we upgrade our Digi equipment and not lose functionality.
Are there any replacements?
Is PortServer® TS 8/16 a sutable replacement for Accele Port 16p?

Kind regards.
