We are looking into upgrading our Data Ontap version to 6.1.1R2 and just wanted to find out whether there are issues with it or not. We have to upgrade it because I want to use the new DS14 shelf and it is not supported in 6.0.1R3. We have our Exchange, MS SQL and Sybase data on it. Has anybody done this upgrade and how did it went. Any input will be appreciated.
