Re: 8.1.7.4 upgrade - 10g or 11

11g does not support a direct upgrade path from 8i using MIG or the DBUA. You would need to upgrade to 9iR2 or 10g to do this. You could use imp/exp to directly move from an 8i database to 11g.

Frankly, 11g has been a touch buggy in it's first release. I'd wait for the first patch set and see how things shake out. There are a number of new features in 11g that are very powerful though (though many of them require separate licensing). If it were me, I'd look at 10gR2 for the first upgrade with an eye to 11g sometime next year.

I'm doing a University session at Collaborate on 11g, and we will talk all about upgrading to 11g in that session.

Hope to see you all at Collaborate!!

We are starting to plan an upgrade of one of our applications which currently runs on Oracle 8.1.7.4 on a Solaris server. The database is about 70 gb and I expect that the entire upgrade process will take between four and six months. The new version of the application will support either Oracle 10g or 11. Is 11g reliable enough that we should consider it instead of 10g?

Will I be able to upgrade the 8.1.7.4 instance directly to the final version or will I need to do an intermediate upgrade?

Thanks,
Peter Schauss
