Large Scale Deployment using open source

[jamaj79]

Hi all, I was just curious to see if anyone has migrated over to Zimbra in a large scale environment using the open source edition? Lets say anyone with over 50-100K users and if so, how has the transition been? Have you worked around the clustering option that doesnt appear to be availabe in the open source edition?

Thanks!

I don't know that anyone has implemented the open source version on such a scale yet, but I think the first problem you would run into is the lack of hot backup capabilities in the open source version.
