    EBS Migration from 12.1.3 to 12.2.5



      We are in the process for migrating our actual EBS environment that is EBS 12.1.3 running on Red Hat Linux 5.5 with database version

      We want to move everything to EBS 12.2.5 on Oracle Linux 7 with Database



      I was thinking maybe of doing the migration in 3 main steps that can be done at different time to reduce downtime and complexity of the migration:



      1- Migrate Database to

      2- Migrate EBS to 12.2.5

      3- Migrate OS to Oracle Linux 7



      Anyone have experience with this kind of migration or any recommendations/issues. Is it better to do it in different order or maybe to do everytinhg at the same time?



      Any help appreciated.
