Anyone do this before ?

ZENworks v6.5

Server1 = Desktop Management Server

Server2 = Middle-tier server

Server2 is old, no longer under warranty, and while maxed out as far as
harware features go, is under equipped. Therefore, it is being replaced.

Server3 = replacement for Server2

Do I just need to install Middle-Tier ZEN on its replacement, and then
re-install ZfDAgant on all workstations, with the "MT-Server_Address"
qualifier pointing to Server3's IP address ?

Do I have to do anyting in eDir or eleswhere as far as removing Server2
from the ZEN environment.

Thanks for any forthcoming advice or suggestions !
