How to update Server Avalanche IP address?

Hi All,

       We need to move our Avalanche server to a new site so the IP address will be changing.  We have 250+ devices currently pointing at the exising IP address. 

Could you please advise how we could migrate from one IP address to another with minimal impact?

I have been looking at the "Network Profile tab,  Manage IP Address Pools" - If I specify multiple IP addresses here will the devices use this list to replace the "Server Avalanche IP" in the enabler?

Thanks,

Dave
