Our small business currently has an existing domain (2003 & 2008 Servers) that we want to phase out and bring in a new Windows SBS as our primary domain. When all is said and done, we want to completely phase out our existing domain altogether. What is the best way to go about this, gracefully? We are a small company of 10 employees, so, it is not a big deal to re-create accounts, etc.
In our existing network, we have a Fortinet router, a Windows 2003 server (DC) that provides DNS, DHCP & VPN. We also want to host Exchange for our internet domain on the SBS server, something we currently do not do.
We already have the Windows SBS installed. Do we need to set the SBS up on a different range of IP addresses? Our current range is the default 192.168.1.0 class C. Should we configure SBS to use a different range, perhaps 10.10.1.0? If so, how does that mix in with our existing network?
We do have people / employees in another state that VPN to our office, so, we do have to be careful not to disrupt existing activity in our production environment, but, this just about goes without saying unless we were a completely new company, which we are not.
Thanks for any input and advice experts!
