Moving the server or the switch? Moving server, no problem, part of L3 routing and not WLAN. WS5100 with AP300 only to L2 bridging.
If WS5100 and AP300 in the same L2 broadcast domain, no problem. Also if you change the IP, important is the L2.
Not sure what version you use. But with L3 adoption you need to change the DHCP option, if the WS IP change.
