Hi, this is my scenario
I have a client where the parent company has split into two smaller companies. The two companies will be at the same physical location for a year, then company B will split off and want to move its servers to the new location. So I am trying to make this a seamless transition for both companies.
Company B will have it own domain and exchange server. Windows Server 2008 R2 and Exchange 2010. There will be trust setup between A+B for sharing files etc. Company A is also running Windows Server 2008 R2 and Exchange 2010.
So my question is this? I understand the Server side of the equation but I am not so sure of the network topology to get them both talking without network collisions etc. I have a single watchguard firewall with two interfaces for the first company and I am hoping to use the second two interfaces(wan/lan) for the second company. Will I need to setup VLANS? I am also guessing I would need to setup a new IP scheme and change the subnet for company B.
Sorry I am little confused on how to roll this out, any help would be greatly appreciated.
