Hi @sarrankanp50398
Yes if your server B is already setup and running then you can to do only below steps. Assuming by what you mentioned it looks the server B is already working for you and is installed till the point of instance creation which is done using account "internal". Remember there is no addtional database setup required since we would be pointing to the same database.
Step1- Copy the two files config-instance.xml eg (config-Adobe.xml) and serverconf.xml files from server A to B where you want to replicate the environment. (Take a backup of two files before you replace them with files from server A)
Step2-You Need to make sure the instance is having the same name and restart the services for IIS and ACC on server B.
This is how it is used in our environment which has multiple application and web servers and also when servers have to be migrated as per requirement from client. This way all objects like operators, workflows, schemas, etc are replicated to the other servers.
If server B is not build yet. Please follow the high level steps which i have listed to setup and configure assuming it is windows setup for which you need to install below software with admin rights access. You might have to reach your internal staff or admin if in case they look after the setup.

Install Oracle client
