I need to move my existing DHCP scope to make room for a VOIP phone system. My existing scope is 192.168.25.25 - 192.168.25.99. The current lease timeout is 3 days. Can I simply change the scope to 192.168.25.110 - 192.168.25.199 without deleting and recreating? How will this affect those current leases? I've already verified that the new planned DHCP range addresses are available and the VOIP system won't be in place until Nov/Dec. Any help would be appreciated, thanks.
