Hi @aehtibarov there are a couple of ways that I can think of. You could use CDO to manage both ASAs, this way you can import the current configuration including objects, access-lists etc and then apply these to the DR ASA. Any future modifications to objects etc would be applied to both ASAs.
Alternatively you could create a python script to extract the configuration and replicate, although that would be more bespoke to your environment and would take more effort.
