New Post: Manual upgrade from v4.3 to v5.+

Hey papdoble151

I was able to successfully manually upgrade from 4.3 to 5.1 manually. However, upgrading to the current newest version: (Orckestra CMS 5.5) seems to be an issue. The steps I've taken are the following:

1. Overwrite the Bin folder
2. Overwrite Composite folder
3. Merge the necessary lines from /Global.asax
4. Merge the necessary lines from /AppData/Composite/Composite.config
5. Merge the necessary lines from /Web.config
6. I then copied /Bin/Composite/Generated.dll from 4.3 to 5.5
   

The steps worked perfectly to upgrade from 4.3 to 5.1 but it does not seem to work from for 5.5.

The Error I get is:
Missing a field 'Id'
which comes from:
C:\inetpub\wwwroot\CMS-Foundation\CMS-Foundation-master\Composite\Core\Linq\Extensions.cs

Do you have any idea what the problem could be?

Many thanks!
