I have 184.108.40.206 database. I need to upgrade to a higher version either 220.127.116.11 or 18.104.22.168. Which one I should upgrade it to? Im not going to upgrade on the same server. I will have to do it in a new server. So how can I proceed with the upgrade? Export/import? DBCA? Manual upgrade? What is the procedure to do this?
Same as above question except that this is another database but 10g. Which version I should upgrade it to and how to?
I will be moving from OEL 5 to 6 or above.
Downtime I will get over an weekend.
No change in character set or licensing features.
Database size is approx 50 GB.
This is only development instance and not prod.
Should I install 12c database and then import everything from 11g to 12c database or run DBUA?
