Hello Eric,
Thanks for contacting Cisco support community centre.
I hope you are doing well. I am really sorry for inconvenience caused and delay in response. There is no tool to generate a configuration file for RV325. Only way is to configure one RV325, download backup file from it and upload it to other one, for that all router should be on same firmware version or you have to directly configure on required router.
Regards,
