I am wondering if it is possible to SAFELY downgrade ZCS 8.0.2 back to 7.2.1, the version ,which I upgraded it to 8.0.2.
Why should I do that?
Simply because I keep receiving complaints about non-intuitive ZCS 8.x version user webmail interface. I know and I admire programmers hard work, I really do, but I cannot help if users daily complain how to switch back to "nice web interface with descriptive icons" and to "user friendly search" back in 7.2.1 version. So, this is PRODUCTION with thousands of users, and I am asking for your experience with downgrading ZCS 8.0.2
