Thanks. It's the data comparison difference that has me concerned. If the only problem will be with Binary "John Doe" does NOT equal "JOHN DOE" and after changing the collation "John Doe" does equal "JOHN DOE" that's ok because we want to have a match in this situation. But I can't think of examples where case sensitive comparisons may be necessary. I've warned the business users they may see a difference in sorting, but I'm not sure what other warnings to provide outside of a possible dip in performance during large search operations.
