I have ebs 12.1.1 and 184.108.40.206 running. Now i want to upgrade it to EBs 12.2.6
In server B
using active duplicate database feature, i will migrate the Db(220.127.116.11)from server A to new server B. In server B, i will upgrade the Database to 18.104.22.168. Then i will layout the EBS 12.2.0 file system and then upgrade
In this case, users will be able to use the existing EBS 12.1.1 and in parallel we can accomplish our upgrade
Sorry for the confusion. When i say in parallel, i meant to say that once i create a database in destination server using active duplication(for development phase only), users will be accessing the existing EBS 12.1.1 env and DBAs will be doing the upgrade activity in the destination server. And in destination server, we will layout the EBS 12.2 file system using the existing database(created by active duplicate method) and proceed with rest of the steps.
basically we are doing a migrate and upgrade method for our first development phase. Is this feasible?
