Powershell script that will copy node and node event history from one SolarWinds database to another

Do you know of a Powershell script that will copy node and node event history from one SolarWinds database to another?

For various business reasons both databases are in use.

So we need to copy node and node event history from one SolarWinds database to the other.

We can't just overwrite the existing database.

This Powershell script and SDK is very close but does not copy node event history.

Thanks
