I am having a unity server already running for one of our customer. But now we have to introduce one more unity server to build failover and take exchange and AD which is currently running on the unity server to the new server.
Challange is that the new server which i have to introduce has to be the primary server and existing one to play the role of secondary.
Though i have thought of taking the backup of existing unity server by DiRT and then restore that to the new unity server. Once restore is succesful, and at the same time move the mailboxes to the newly build exchange server and point the new unity server to the new exchange server and build the integration with callmanager. If everything will go smooth, then i am planning to scrap the existing unity server and build it from scratch.
I am not really sure whether this is the right approach and do i need to take some more precautions before hitting the actual implementation.
And one more thing i would like to know is that while restoring the backup, IP address and hostname will not be same as the old server. Will that have any impact on the restore???
Any suggestions will be highly appreciated.
