Do you have a valid license?

Yes i have evalution license key.

But I would guess that it's not valid anymore. I mean it's an evaluation license and you're talking about Confluence 2.5 which has been launched like 6 years ago. Check your license details

What do you mean by installing 2.5? Do you have 2.5 installed an running ? AFAIK you'll have to purchase a license, update your license information in Confluence and start updating...

Thanks christain..

I am trying to upgrade confluence 2.5 to 5.0 version. Just started installing with 2.5 version.

I am getting this error before it goes for asking license key .
