Planning on purchasing the Netwrok Professional Edition and currently evaluating its trial, the question of a fallbackserver occurred. Our main goal is to provide a hosted ZCS environment for customers, with the possibility to login to an alternative webinterface and/or use an alternative POP/IMAP server when our primary server goes down.

In concreto, we have the following questions :
  1. is this possible at all with one license ?
  2. is there a possibility to synchronize both servers in an automated way ?
  3. is there any documentation on this ?

We are using the Ubuntu 6.06 LTS server.
