It seems that this satellite is going to slot A3 of the constellation, replacing SVN38 (GPS IIA-19, launched November 1997) - SVN38 will then move to slot A2 as back-up. However earlier reports puts slot D4 as the satellite's final destination - which one is correct? And what will happen to the other satellites on plane A after the launch?

OK from William's article it seems that:

Slot changes:

SVN64 (IIF-5): A3
SVN38 (IIA-19): A3 -> A5
SVN39 (IIA-12): A5 -> A6(?)

PRN changes:

SVN64 (IIF-5): 30
SVN49 (IIR-20): 30 -> 06
SVN36 (IIA-15): 06 -> non-broadcasting

Is that correct?

Launch is scheduled for this evening at 8:40 p.m. EST at the opening of a 19-minute window. GPS IIF-5 is the fifth in a series of next generation GPS satellites and will join a worldwide timing and navigation system utilizing 24 satellites in six different planes, with a minimum of four satellites per plane positioned in orbit approximately 11,000 miles above the Earth’s surface.
