EBS Upgrade Part 4 - 11.5.9 Database 9i RHEL 4 to EBS 12.2 Database 19c OEL 7
This is going to be challenging. These decisions involve a lot of understanding about the complexity underlying. So we are on 10g 32-bit on RHEL 4 and want to move to 11g. The best possible route after reading a bunch of oracle documentation came to a conclusion that will build a RHEL 5 OS and do a OS migration. Then post the migration decided to upgrade the database to 11g.
Well there was a limitation for me and may not for all. I need a RHEL 5 server which I do not have. So I had another laptop where I spinned off a Virtual Box and Installed a Guest OS 5.11.
