I am migrating 3 standalone databases from one old machine running RHEL 5.11 and
Oracle Database 126.96.36.199.0.
The new machine has better processers, RAM, storage and running RHEL 7.2.
Oracle recommended to reinstall oracle software instead of copying binaries.
My questions are:
1) Is it better to install same oracle version 12.1 on new machine or
shall I install the latest release 188.8.131.52.0?
2) If I installed Oracle 12.2, do I need to do any rebuilds or any extra work for the database files I will be copying
from old machine to new machine?
