Calculate shape field through a table join

I have a line feature class for which I want to overwrite the geometry with new, more accurate geometry from another feature class. I wanted to do this by simply joining the tables and calculating the original shape field to equal the shape field from the joined table. This does not seem possible. Are there other suggestions for replacing the geometry of one feature class with another when you have key fields to link the features?

Also - The original feature class can not be exported or replaced. It is a versioned SDE feature class that must retain all original ObjectIDs.
