Exp/imp of a 200GB database is possible, but I'd think the time required would be the long pole in the tent. I'd say your looking at at least a 4 day weekend at best and only if you used direct mode. Someone has hinted that you can simply move the datafiles from one box to the other. Well I'd not loose the original system before you prove that. My experience with database file from Solaris to HP-UX has been a 100% loss of data. Granted that was on a much earlier version of Oracle (6.0.x).

Hi all:

We are considering migration of an Oracle eBusiness Suite 11.5.8 from HP-UX 11.0 to Solaris9.

I'd like to know if anyone has done this and how daunting the task is.

Are there any 3rd Party tools which can help out?

Coming to the conventional approaches:

What do you think of Export/Import of a 200 GB database? 1a. How much time will it take? 1b. Any strategies for cutting that down?
How does CTAS over dblink compare to Export/Import?
Is there any tool that converts Oracle datafiles on HP-UX 11.0 to Oracle datafiles on Solaris 9. If so we would just need to recreate the control files on the target database and we are done.

Any suggestions, pointers, words of wisdom are greatly appreciated...

Thanks & Regards,
Sashi
