Chaning the datatype

When we change the data type of a field, then the new data type will not reflected in old documents. To change the data type in the existing documents we have 2 options
1. Open and Save all the documents.
2. We can have background agent to do this.
Here is the logic,

• Create an item for the existing field
• Copy the items content
• Delete the item
• Create a new item for the same field (The new item will have the new data type)
• Set the old value in the new item
• Save the document.
