Colin said:It's a little more complicated than that. There are a LOT more stars in RECONS and Hipparchos than in the old Gliese 2, and some of the positions have changed (more accurate). Among other issues, Wolf 359 (Nyotekundu) is 7.8 light years away. Using new data means no Arms, which greatly changes everything. No chokepoints, no strategic systems, and a clear run from Cucaracha space to Earth.

Now we find that we have better data, and feel compelled to use it, but that could potentially break the setting. My position would be to favour preserving the setting, and use the new data only as far as it suits.
My recollection is that the both the reality of the star list and the resultant arms were key to the "feel" of 2300AD when I bought it. With the benefit of two decades of hindsight I would say that the arms are probably more important to 2300AD than the reality of the astrography.
With that in mind I'd suggest that you need a cost benefit analysis - how much time and effort will it cost to "impose" arms on modern star lists so that you can claim the benefit of real data (at least until such time as they issue the next revision). If its going to take a lot of time and effort I would drop it and put the effort in where the benefit would be greater. If its doable by (say) tweeking stutterwarp ranges and changing the stars of a couple of colonies then fine.
