Hi Oliver,
When you are saying "Host configurations", I believe you are referring to the NCM Host configuration captures?
As the host configurations are stored in the SSdb and are compressed / encypted and are non human readable, the best way to collect the host configurations would be to export them via a Global Synch Task from NCM.
The option to export all of the configurations during a Global Synch Task would be:
Export Unique and Global Sync Configurations
This would export all of the configurations into text files during a Global Synch Task
Doc link for reference
Network Configuration Manager Configurations - CA Spectrum - 10.2 to 10.2.2 - CA Technologies Documentation
Best regards,
