Dose move influence I485?

My I-485 is pending in Texas service center, but moved to New Hampshere several months ago. Should I transfer my case to Vermont center or just keep it in TX? Does this influence my case approval? One of my friend moved to Philadelphia while his case was pending in TSC, his case was delayed because it was transfered from TSC to VSC, then to the local office, his RD of I485 is Jan, 2000, but still pending. Does anybody have this experience? Please give me some suggestions. Any info is welcome!! Thank you so much!
