I am asked to upgrade mysql 3.23 to 4.0, because the final objective is to upgrade to 5.0. I have several questions. If you have some similar experience, please give me a hand.
1. Can version 3 client access version4/5 server?
2. What needs changing after upgrade to 4.0 or 5.0?
3. We use perl and java. Do I need to do something for these language specific drivers?
Best regards,
