Swapping Receivers between rooms. - DirecTV

My initial install was done 8 years ago. My DVR is in the living room connected to coax while the gateway is in a bedroom. I am looking at moving the DVR to the bedroom so I can connect it to the gateway via cat5 cable and moving the STB from the bedroom to the living room connecting via coax.
Are there any issues with this? I have read it is best practice to have the DVR connected to the gateway via Cat5.

Also, are wireless receivers better than 8 year old STBs connecting thru coax? Does it make sense to change the old ones out? I only have 1000 sq feet so wireless signal is not an issue.
