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.
That would be a thorough way of doing it. But simply running a calbration on each, and checking the Info window on each will give the native white and black luminance of each monitor, so you can choose target white and black that both can reach.
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).
That would be the most comprehensive way of doing it, but simply choosing a K value for both would be more typical...

same gamma. I'm not sure about the best compromise for Luminances, one
monitor being old and all that.
There's no practical way of compromising... you set the target luminances for values both can hit.
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)...
As long as you are sure the second monitor can hit the target values for the first, that will work fine. Typically starting with the older or more limited monitor is all that is needed to make this work...
