Hi, I have my tank for 7 months, can I adjust the position of the liverock inside the tank? will it cause any problem to the livestock?

You mean restack your LR's?? the main problem is Stress to LS in your tank. BUt if you are reffering to water quality (swing), I dun think there will be , as your tank is 7months old..But N03 will increased slightly as you distrub the sandbed

I did that to my tank once and I experienced another cycling! Amonia & Nitrate spikes!

I would think it is alright to adjust a little but moving too many LR will firstly stressed your LS and secondly create another cycling of the tank.
