A person came up to me today, and asked if SQL 2008 and SQL 2008R2 can reside on the same OS. I asked them why they would even consider trying to do such a thing, since both versions are so close to being the same. But then I had to tell them that I was not absolutely certain. I know that you can have SQL 2000, SQL 2005, SQL 2008R2 and SQL 2012 on the same OS, which I have currently on one of my boxes. So I would think that you could not have. Was I correct, or incorrect?
Thanks in advance for your assistance
