Our server at work is getting full, we have two 500gb hard drives running in raid 1 at the moment but the drives are getting full. The server has more bays and I want to add some bigger hard drives to it and also try to run them in Raid 1 as well but just as back up drives. But I am going to need to transfer the information from the current hard drives to the new ones without losing anything and then keep backing up to the new drives. What is the best way to go about doing this? I hope this all made sense lol. Thanks.
