OSX Upgrade on 2006 xserve

I have an xserve 2006 (emc2107) running MacOSX 10.7.2 Lion Server. I read that it can be upgraded to 10.7.5. I burned a copy of 10.7.5 client upgrade and 10.7.5 server upgrade. Here is the good part, I mislabled the disks. So I used 10.7.5 client upgrade on the xserve running 10.7.2 Server. Is there a way to recover my server os? I hope that just installing the 10.7.5 Server upgrade will work but I don't wanna make things worse. Basically if anyone can give me some advice I would greatly appreciate it.
