Avoiding break of cms project starting

I try to change a page property type from string to XhtmlString.

I know this gives InitializationException for the CMS (in some cases e.g. Pages and not Blocks).

-----------------------------------------------------------------------------------------------------------

InvalidCastException: Unable to cast object of type 'System.String' to type 'EPiServer.Core.XhtmlString'

----------------------------------------------------------------------------------------------------------

Is there anyway to force cms to start up and ignore InvalidCastException?

We are on Optimizely 12

Hi Zuf,

Actually, when you change property then content model is synchronized to database to update the change as well. And converting data from string to xhtml string is need to run.

You can rename propery name in case of changing property type to incompatitive type. It is simple way to solve this issue.

You can try using MigrationStep with RenameProperty function to migrate the content from string to XHtmlString.

thanks for your answers.

@Sujit, as far as i understand the MigrationStep only works for renaming and not for changing type?

You are right @Zuf. MigrationStep wont work for this. I believe the only solution is to Create a new property with XhtmlString and then migrate the data from String property using a one time migration script. And then remove the property from code and Edit UI.

Create a new xhtmlstring property, then write code to update the XhtmlString-property from the string property, and finally remove the string property.
