Db migration from Solaris 8i to windows 10g

Question

There is requirement to move db from solaris8(dbversion8170 to window Server 2003 (10204 already installed)
DB is about 80gb big, what would be the best approach ?
I am thinking to create new db on windows, and export and import data.....any concerns/suggestion?

Answer 1

what are other options i can try ?I only mention this approach because you asked. I wouldn't recommend it as a general strategy. exp/imp is the most straight-forward.
We are in the process of migrating from 9.2.0.6 to 11.1.0.7 (11.2 is not an approved standard yet in our enterprise), moving from Solaris to Linux, and consolidating two related instances into one.
We had to handle some unique situations due to our consolidation, so we did a lot of the steps manually that exp/imp does for you. A side benefit of this extra work is the actual down time is can be less than exp/imp itself, and avoids the need to dump all the data to disk and read it all again. We have about 500GB to migrate. It is a lot more work than a simple exp/imp, and is probably not be worth the effort for a single 80GB instance.
Our steps (oversimplified, there are more details than this) :
Set up the new instance and configure storage
Create users and roles in new DB
export structure only (using 9i exp)
import structure only (using 11g imp), without indexes or constraints
copy data (insert /*+APPEND*/ into.. select * from ... over a database link)
create indexes and constraints
Handling LONG data, materialized views, interdependencies between schemas each presented their own special circumstances I had to deal with.
The other path to get from 8i to 10g (mentioned only for academic reasons) is do a series of upgrades-in-place to get from 8i to 10.2.0.4 then use cross-platform transportable tablespaces to go from Solaris to Windows.
