Girish,
Thanks for you heads up. The documentation that I've read thus far spoke of SSO and that it will installed as part of vCenter upgrade to 5.1.
However, I haven't read anything about the DB being upgraded during the install. Our DB is a separate physical Microsoft SQL 2008 server. Does that still apply? If yes, can you point me in the direction of any documentation that outlines it? I will need that to have for my upgrade plan to be approved by our Change Advisory Board.
Thank you.
