Changing Workgroup Name, will I lose data?

I have 3 Readynas units all with firmware 6.95 on 2x 104 and 1x314. Theyt all have a lot of photos and music I have digitised over the years , and when I bought these and set these up over the years, I forgot to alter the workgroup to match my router and PC's. So now I have 4 different Workgroups "Volume, Workgroup , Home and Family, when looking at the windows network. My simpleton question is if I rename them all to the same name now, will I lose any of my data on them, and will I be easily able to reconnect to them. I am not changing the static IP  I set them up on.

I suspect this is s a really simple question and answer to most, I know it did not affect any of my PC's when I have done it, but I also know I have had some fun with ReadyNas units in the past, so want to be extra careful.

Many Thanks for your time reading this, and I am grateful for any advice.
