Re: move 9i r2 database on host 1 to 10g r1 on another host

Let me add another option:

If the servers are running the same OS on the same architecture you should be able to create a new DB on host 2 and then use transportable tablespace to copy the datafiles to host 2 and plug them in the new DB.

You get the advantages of a new, clean DB but the copying the datafiles should be faster than exp+imp.

Hi Martin,
I read through the link that you provided. Personally, i woud prefer DBUA to do the upgrade. To my understanding, DBUA requires the database to up. In my case, there are no 9i binaries on Host 2. Host 1 is completely 9i and Host 2 is completely 10gr1. So I cannot bring the 9i database up on 10gr1.
In this scenario, I believe the options I have are:
1) to install 10gr1 software on Host 1 and do the upgrade with DBUA and then copy all the datafiles to Host2 later and startup the database.
2) Create a database on host 2 and use export/import from host1 (9i). Whats your say?

Hi Sundar,

you are correct. shutdown the DB, copy all datafiles, controlfiles,
redologs to the same path in the new environment.
don't forget the spfile/init.ora

I found a quite good walkthrough which should help you to perform the upgrade:

I hope this helps.

best regards,
