   I second the "Replace Geometry" tool for this type of update.  I was 
able to create a new way matching the length of the old and then replace 
geometry and join the ends.   One thing to check carefully is for any 
other object which has been attached to the old boundary.  That got me 
where 2 roads terminated on the boundary and each other; that point 
would be lifted and cause a gap in roads for example.
