Using WordPress 2.5.1 datebase

dear all:

i have installed new wp script at my webhost. now i need to upload my old wp database which was based on 2.5.1 now how should i do that on my new wp 2.8

i m technical so there shouldn’t be any problem for me understanding the issue.

the mistake i made rather then i would upgrade my script i have installed it 🙁 this was due to migration of my web host.

looking forward for your response.
