How to transfer user accounts to a new host

I’m spinning up a new IDB instance (1.8.1) and am using Toni Moreno’s syncflux tool to copy the databases across to my new instance (can’t shut the old one down because folks are using it!)
Problem is that I don’t see a way to bring across the user accounts across - is there some approved way to do this, or should I just ‘get brave’ and mirror the _internal database?

Hello @BobX,
I’m sorry I’m not so sure. I’m hoping to get an answer for you soon! Sorry for the delay.
