Backup/Restore from Hardware to Software based

Hello Guys, I'm new with ArcSight ADP, and one of our clients is using a hardware-based (ArcMC, Logger, ESM).

Since the HW-based is already on the EOL, they are planning to have a refresh and knowing that the HW-based is much higher on its cost.

Questions:

1. Is it possible to do the backup and restore from hardware-based to software-based?

2. Can you share some documentation on how to do it.

 

Thanks
