Big error list after upgrade

I upgraded from 1.5.6.4 I went through the process without any issues until I tried to log-in after I got the message that I has successfully upgraded to 2.0. I clicked the link to log-in and got the following:

I am running on a test server so I'm not in a huge time crunch.

There's no upgrade script available so you're going to struggle going from v1.5.x

There is a upgrade-topic made sticky at the top if this forum called: Do NOT upgrade to 2.0, yet!
