Hey Vasilis, could you show the code that is failing?

You can update your templates and handle the new values (we call them UDI, Umbraco Identifiers).

Here's some code that can pretty safely convert UDI's back to a numeric id:

@{
    var listOfValues = new List<string>();
    listOfValues.Add("umb://document/4fed18d8c5e34d5e88cfff3a5b457bf2");
    listOfValues.Add("1233");
    foreach(var val in listOfValues) 
    {
        int id;

        // try to see if the id is a number, if it is not, try to parse
        // it as a UDI and then get the integer Id from it
        if(int.TryParse(val, out id) == false)
        {
            try
            {
                Udi udi = new GuidUdi(new Uri(val));
                id = Umbraco.GetIdForUdi(udi);
            }
            catch (System.FormatException) 
            {
                // this doesn't seem to be a Udi either
                // do something to handle the error
            }
        }

        <h2>Id is @id</h2>
    }
}

Remember, this is just an example, I am assuming you already have a list of values, so this is just there to test that the code works.

If Umbraco.GetIdForUdi(udi) doesn't work for you, you might have to get an umbracoHelper instead, so that code changes to:

var umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
Udi udi = new GuidUdi(new Uri(val));
id = umbracoHelper.GetIdForUdi(udi);

However, I can't remember exactly how this would work in dynamic razor, you might need to construct the umbracoHelper like this: var umbracoHelper = new Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);

No problem. You did say the update was done before the summer so I figured you couldn't go back.

Good luck in any case!
