Our web application servers(.Net) are running on two data centers(texas & newyork) which is pointing to one DB server(19c). We are trying to implment zero DB downtime implementation using EBR. During release deployment .net code changes would be deployed one data center at time and parallely DB code changes would be deployed. So if one web server is invoking Pre-upgrade edition DB SP and other web server would invoke Post-upgrade DB SP.
Is it possible to invoke both Pre-upgrade & Post-upgrade editions SP during this rollover deployment time?
Note: Application do not want to alter session to set editions
