We are currently on Discoverer Version - 18.104.22.168.0 and we are using this (in Sustaining support mode) on Oracle Database 12c and Oracle EBS 12.1.3. We are planning to upgrade our Database and EBS versions to 19c and EBS R12.2.8 sometime later this year. We would like to know if this will work or there are known issues that this will fail. as per Document ID 2674063.1 : Oracle Discoverer 22.214.171.124.0 Certification With EBS R12.2, Discoverer 126.96.36.199.0 is certified and supported with EBS R12.2.8 . Please suggest.
