We are planning for JIRA/Confluence Migration and upgrade.
Confluence and JIRA are using Postgres 8.4.20 database currently.
We are moving from Postgres to ORACLE now for both the applications.
JIRA Current version[6.3.12] , Confluence[5.6]
As per the information from atlassian, we need to go to Oracle 11G(11.1,11.2) and then to Oracle 12C.
Which Edition of Oracle we need to choose there ? "Is it Oracle Standard Edition" or "Oracle Enterprise Edition" ?
