LTO3 to LTO5 (and another one)

We are getting ready to upgrade our backup heads to accept LTO5 (from LTO3). Is there anything we need to do to prepare for this or will NBU just "see" it.. I'm running this on Windows server 2k8 R2 and NBU version 7.5.0.6...

Another little question is the previous owner had email notifications come to him for cleaning (I'm a new employee).. I've looked at Host Properties-->Global Attributes, and see the email address but is that for cleaning reminders too???
