When I tried a direct upgrade I got a different error message, so I did some research and was following this blog post (http://www.blix.co/blog/2014/6/5/follow-the-path-upgrading-umbraco-from-v4-to-v7.aspx) of a very similar upgrade to mine.
The error I got when upgrading directly to 7.5.6 is:
Could not load type 'umbraco.presentation.umbracobase.requestModule'.
It looks like umbraco.presentation.umbracobase.requestModule is a part of an old version of Umbraco. You may need to remove it from your web.config (with such a major Umbraco upgrade, you can expect a ton of changes to the web.config).
Hmm, I replaced those lines with the ones suggested and got a new different error.
I think you're right I would just have to go through the web.config for things that need updating.
I've talked to my boss however and he thinks he can make it work with a much lower version as it only needs to work for a short while another site is built.

Hi,
I've been trying to upgrade a site with version 4.5.2 to the latest version with the upgrade path:
4.5.2 > 4.6.1 > 4.7.1 > 4.8.1 > 4.9.0 > 4.11.1 > 6.0.0 > 6.2.6 > 7.0.0 > 7.5.6
But I've gotten stuck upgrading from 4.9.0 to 4.11.1.
To upgrade I did the following:
After the login page loaded just fine, but after I logged into the admin panel I get the error from the title with the following stack trace:
I've seen from other answers to delete and then re-add the global.asax file but I can't find one in the project.
I'm not the developer for this project and haven't worked with Umbraco before but I would appreciate any help.
Many Thanks,
Oliver
FYI, you should not need to perform a bunch of intermediate upgrades. You should be able to go directly from 4.5.2 to 7.5.6.
