Upgrade from 2015 to 2018

Hi Folks,

I am upgrading from Remote Desktop 2015 to Remote Desktop 2018 and when I connect to my ASGRD database it tells me it needs to be upgraded.  I opt to upgrade the database but it is asking for a password. 

I've tried all the passwords that I can remember but I don't have this one.  Is there a way to either recover or remove this password so that I can move forward?

Thanks,

Mike
