Register yourself as a customer on the Qlik website, and the downloads page (probably only letting you download the latest Desktop) will become the full QlikView download inventory application with all QlikView Server releases to choose from.
If you are running v11, you can still upgrade to the latest SR (which is 11.20SR13). But to upgrade to QV12, you must have an active maintenance contract and paid your maintenance fees.
Thank you for your response and sorry for the delay in getting back to you with my feedback.
We are using the partner license and all we have is 'EVALUATION' license with 5 User CAL's, as of now we are in the assumption that it will be licensed to upgraded version directly since we are only upgrading to the new version or do we need to do anything else to get the license for this upgraded version as well? please advise.
Yes it is a blank page and below are the screen shots for your reference.
