I notice you reference your current install is on the E:/ directory. Are you sure you've indicated this is the directory as part of the install?
From the Server Install Guide Prepare for the Upgrade
When i click on the Setup
First thing it does is asks Where to Install
In there i select - E:Tableau Server
as i remember to not put the version number
Than a Prompt comes up that tells
Your Hardware meets the minimum requirement for a Trial
below are the two screenshots
Also i dont understand, why I am getting a minimum hard ware requirement note- as I ran 10.1.3 on this for 1 year
Is that a typo or are you installing to E:/Tableau Server/Tableau Server as if original install is E:/Tableau Server then there's a discrepancy...?
Can't comment on your hardware spec. Can you be certain you didn't get this same message when you installed v10.1? I don't believe there's been a change in the recommended h/w spec since moving to v10.0.
So I did it on
but it still brought the same prompt
should i still go ahead and install?, will it migrate my repository from 10.1 folder?
Is it just the presence of the hardware spec message that makes you think it's doing a fresh install or something else. I've just recently upgraded our low spec POC server from 10.1.1 to 10.3.1, installing to the default location though. I also got the same hardware spec warning which I accepted and the 'upgrade' went through fine, migrating all the data over.
I'm assuming since the hardware is below spec that this isn't your production environment you're upgrading.
