I'll take a shot at this...

First print out reports for both monitors to see where you stand (run
File/Validat first, then File/Print Info). Compare the numbers and
look what the differences are. Most likely white point is the main
difference. If not then post the results here.

In my opinion the correct way of doing the white point matching is
looking at the "better" monitor x and y CIE numbers in the report and
then creating a New target (on the Select Target screen) for the other
monitor using CIE numbers (rather than the K number) for the white
point target (there's a Custom white point number in there). Select
same gamma. I'm not sure about the best compromise for Luminances, one
monitor being old and all that. 

Run calibration, run File/Validate, print results. See if they get closer.


A shortcut for lazy and careless people like myself is to load an ICC
profile created for the first monitor as a target for the second one
(File/Open target, navigate to the first icc profile)...
