Will an upgrade to 10G hurt my VB6 applications?

[abhijit]

Chances are there will be no problems, most upgrades these days contain new features and better ways of doing things but still support the old features.

The best way to test this though is to simply set it up and run the app!

I had an Oracle 10G Express Edition on windows setup on a test box. The ADO provider used by my application fails to retrieve data in long columns.

Preferably in a lab setting prior to rolling it out into production.

They plan to do this in the standard phased "dev / uat / production" routine.
There is only one developer for my applications. I wanted to have that pre-dev, so I am testing against a local windows box. My database, however is going to be on a 64 bit unix system. I am not sure if this is going to be an issue.

I shall keep everyone posted.
