I followed the instructions on the upgrade from 4.9 to 4.10 on http://our.umbraco.org/contribute/releases/4101/. My ultimate goal is to get to 4.11.9 so I am taking version steps to get to it going for 4.10 first then upgrading to 4.11.9.
I did the following as per the instructions
Upgrading from 4.9.x to 4.10.0
Overwrite the following folders with the folders from the zip file:
/App_Plugins (new)
/bin
/install (remove after the upgrade is finished)
/umbraco
/umbraco_client
/Views (new)
/global.asax (don't forget!)
BUT after I did my upgrad I got a null reference error.

I did the install steps, web.config was updated correctly using WinMerge and the version is showing 4.10
OK there were evidently A LOT of changes from 4.9.1 to 4.10.x. I ended up upgrading to 4.10.1 instead after seeing the many issues people were having with 4.10.1. I also brought over any changes from the Upgrade config document. This REALLY helps out.

What would have caused this issue?
Thanks,
