Hi Dkos24 and welcome to our :)

Don't know if this article might contain a few useful hints? http://www.blix.co/blog/2014/6/5/follow-the-path-upgrading-umbraco-from-v4-to-v7.aspx There are some tips about some SQL scripts to fire.

Hope this might help.

Hi Jan,

That's actually the guide I followed while upgrading Umbraco :)  I did have to use those SQL commands to upgrade from 6 to 7.  But those warnings came up anyway so I revertred to a v6 backup to try again.

Thanks!

Hi Dkos24

Ah ok :) Have you also read this? https://our.umbraco.org/documentation/Installation/Upgrading/v7-upgrade

Hi Jan,

I have and the part that I think I am having issues with is this part:

Guid -> Alias mapping

There are several database changes made in v7, one of which is the change of referencing a property editor from a GUID to a string alias. If you have a legacy property editor that you'd like to map to a new v7 property editor you can add your custom GUID -> Alias map during application startup. Do do this you'd add your map with this method: Umbraco.Core.PropertyEditors.LegacyPropertyEditorIdToAliasConverter.CreateMap

I don't understand how to do this part.  We have legacy custom content and I need to be able to map it so v7 can understand it.  When I ignored the warnings and upgraded anyway, it caused issues when we tried to upload new content.

Thanks!

I've been trying to research this issue over the weekend and haven't had much luck.  If any one has any more insight into this or has fixed this issue themselves any help would be greatly appreciated.  

I think we just need to convert our custom data types so v7 knows what they are.  If I am not making sense please let me know and I can expand on our issue.

Thanks!

I've just tried to do this:

public class RegisterEvents : ApplicationEventHandler
    {
        protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            Umbraco.Core.PropertyEditors.LegacyPropertyEditorIdToAliasConverter.CreateMap(new Guid("71518b4e-b1a5-11dd-a22c-8aaa56d89593"), "x1");
            Umbraco.Core.PropertyEditors.LegacyPropertyEditorIdToAliasConverter.CreateMap(new Guid("04202ffa-bb67-498b-b67d-0311f68dcae1"), "x2");
        }

    }

But still got:

• Property Editor with ID '71518b4e-b1a5-11dd-a22c-8aaa56d89593' (assigned to Data Type 'a') does not have a valid GUID -> Alias map. It will be replaced with a Readonly/Label property editor.
• Property Editor with ID '71518b4e-b1a5-11dd-a22c-8aaa56d89593' (assigned to Data Type 'b') does not have a valid GUID -> Alias map. It will be replaced with a Readonly/Label property editor.
• Property Editor with ID '04202ffa-bb67-498b-b67d-0311f68dcae1' (assigned to Data Type 'c') does not have a valid GUID -> Alias map. It will be replaced with a Readonly/Label property editor.
• Property Editor with ID '71518b4e-b1a5-11dd-a22c-8aaa56d89593' (assigned to Data Type 'd') does not have a valid GUID -> Alias map. It will be replaced with a Readonly/Label property editor.

Where do I go from here? I thought I'd set up the maps? Are they invalid, then?

is working on a reply...
