Hey,
If I understand you correctly, you want to achieve the following thing:
-> You have a R80 SMS with objects and policies
-> You have another SMS, that is running R80.10
-> You want to move the objects and policies from the R80 SMS to the R80.10 one
There is a tool, which comes preinstalled on Gaia, it's called "migrate export/import". It basically does just what you want to achieve. So "migrate export" creates a backup of all Check Point configurations, without operating system information. You will receive an output file, that can be imported via "migrate import" on the R80.10 device. You have to keep in mind, that with newer gaia versions, also these pre installed tools may have some changes and adjustments. Therefore you should copy the migrate tool from the R80.10 to the R80 SMS in order to create a backup, that can be imported without any problems onto the R80.10 SMS. More information can be picked up from here.
Regards,
Maik
