DBUA to upgrade from 10gR2 to 12cR2

Recommended Posts

Can we use GUI tool DBUA to upgrade from 10gR2 to 12.2.x.x? 

Well, I have gone through https://docs.oracle.com/en/database/oracle/oracle-database/12.2/upgrd/upgrading-oracle-database-upgrade-assistant-dbua.html#GUID-BBF591A5-EB02-405A-9F99-572429838C73 but exactly did not find the answer. It seems to me had the direct upgrade been possible from 10.2.x.x to 12.2.x.x, upgrade through DBUA could have been possible. Kindly validate my understanding as I am new to DBUA.

Thanks....

Hi, And welcome to the forum!  To be safe, I always go through each intermediate release.  Each release has data dictionary updates, and the safe way is to migrate to 11g and then 12c:

However, there are tricks for upgrading with multiple releases:

This may help:
