I am implementing disaster recovery in AWS . My application is deployed in us-east-1 and now as part of disaster recovery I wanted to create same infra in another region . Now i have challenge regarding reusing https certificate of load balancer from primary region to new region(us-east-2). Can I do how? I am not able to see proper AWS docs.
You can't reuse the exact same ACM-issued certificate across regions. The procedure in this case is to create an identical certificate in the additional region.
