Hi guys, We've recently undertaken an upgrade of an Umbraco solution and had some problems which I was wondering whether anyone had experienced before, or might be able to suggest why it is happening? I have upgraded Umbraco solutions successfully in the past and not seen this before.

Our client is on version 4.9.0. We are targeting version 6.2.5 (deliberately not going to v7 yet for various reasons). I first upgraded from 4.9.0 to 4.11.10 to get the solution up to the latest version of 4 before proceeding to v6. Generally this seemed to go well, but unfortunately I noticed that following the upgrade some of the pages were missing content when compared to the non-upgraded (production) site.

I checked in the content table in the database and sure enough some of the XML elements had no string content when compared with the original site, so it's like the upgrade process has deleted some content elements.

Has anyone seen this before?

Thanks
