We would like to rename a GW library.

I have tried to rename a test library object and it wouldn't let me,
whcih I can live with. I found something on another site that said that
you could change the Display name, but it was a bit "flakey".

Is this the only way to "rename a library"? If so is there anything I
should keep in mind or do or not do before I change the display name?

Thanks in advance
