Hi

I am trying to migrate an old printserver from one samba4 (4.8.11 on CentOS-6) server to a newer one (4.11.2 on CentOS-8)
using

net rpc printer migrate all

The migration of queue, forms, securitty, settings works, during the migration of the drivers (net rpc printer migrate drivers)  the command dumps core at the first driver

Here a level10 output

     spoolss_AddPrinterDriver: struct spoolss_AddPrinterDriver

It there somthing wrong with the monitor_name?

I have tried the command with a different system/driver (both samba-4.11) and  I run into a similar problem
