Anders,

How did you upgrade? and what was the process?

Mark.

Hi

I used :

http://our.umbraco.org/wiki/install-and-setup/upgrading-an-umbraco-installation

• Copy your current files and database to a new website, never upgrade a live site, you never know if something breaks, so do a full copy and upgrade that
• Get the latest version
• Check for package compatibility
• Examine your configuration files, the web.config, the files in /config and some other core umbraco files, look for any changes, preferably with a diff tool like http://winmerge.org/)
• Copy over all binaries and umbraco system files
• Transfer your config changes to the config files in the upgrade
• Open the root of your website, the installer should now launch automatically and perform the database upgrade.

THANKS!

Anders,

Does this post help?

I have the same issue. When I upgraded my site from umbraco 4.11.8 to 6.1.1 all document types were missing.

So try to upgrade it again to 6.0.0, still same. Installed the fixpath package then run it, got the following error:

Server Error in '/' Application.

Anyone got any ideas to fix this? thank you

This happened to me aswell, reverting back for now while I try to find more info about exactly what happens / should happen in the upgrade from 4 to 6. In my case I have a rather old site, even with legacy xml schema. Is that even supported?

I've got this same problem, I've upgraded from 4.11.10 to 6.0.0 and my document types have disappeared with the following error when I try to expand the document types folder:

and my content nodes are empty and returning this error when I try to reload the nodes:

In case this helps anybody else, I managed to fix this problem by looking in the database table cmsTemplate - there was a few templates with '0' in the 'master' column. I changed the 0 to null (ctrl 0) and it fixed my problem.

is working on a reply...
