Im updating an item and getting the version of this item to input its value in another list.

The big problem is that I nee to verify if a field on the afterproperties is diferent of the new value in the ItemUpdated.

Simple Question 1:
How can I verify (in ItemUpdated) the original value of a field(column) ?

Simple Question 2:
How can I do an UPDATE on the ItemUpdating without receive conflict message?

Thank you

:)
