address changed--> impact on next fingerprint??

Hi, my 485 pending > 180 days, I am moving, changing address and job. My 1st fingerprint was done in Nov 2005.

Since my 485 is still pending, i assume my 2nd fingerprint should be due soon in Nov 2006. Since I am moving, how would my address change affect my 2nd fingerprint? My wife will be in my old address and I will be in different cities for the next couple months, is it best for me to fly back to my old address to do the 2nd fingerprint, or do I have other choices?

Thanks a lot for your help
