Will my new MBP have the same IP address if I use Migration Assistant?

Hi

One of the options using Migration Assistant is transferring Network Settings. I never enable the setting and even when I have they don't transfer anyway. Clearly if you're in a network environment where IP addresses are assigned dynamically both models wont have the same IP address if they're connected to a network whilst the transfer is taking place. Besides if you tried to transfer network settings from the older one to the newer one you'll get an error saying it could not be transferred. In my experience that's what I see. The rest of the Migration happens irrespective of the error or non-transfer of Network Settings.

Another way of looking at this is to make sure both models are not connected to the network at all and use a firewire cable to target disk mode the older model to the newer one. Migration Assistant will do its stuff regardless.

HTH?

+"are you saying that when I first start-up the new MBP my home wired and wireless internet setup will assign an IP number to the MBP that will be different from the existing MB?"+

Yes. Most 'ad-hoc' home networks will have 'something' handing out IP addresses. Typically this will be a Router or possibly Router/Modem combination depending which kind of DSL Service you have. In an environment like this the Router/Gateway will be the DHCP Server. If you're not manually assigning IP address this would be the case. No DHCP Server AFAIK hands out the same IP addresses to two or more separate devices connecting to the same network. If you are manually assigning IP Addresses you still would not do this. Even if you did a warning message would appear telling you the IP address was in use. This is typical of the sort of basic networking most home environments have.

+"Further I should then use Migration Assistant but I should NOT ENABLE the option to transfer network settings?"+

As already mentioned whenever I've tried this they never transfer anyway. In which case don't bother selecting the option. If you're using firewire cables you don't have to have them connected to any network at all.

It's always a good idea to turn on anything new and test it. It's not impossible for there to be a hardware problem. It's rare but it does happen.

This could be slightly misleading because there is more to network settings than just the IP address. For instance, there is the IPv4 configuration type itself (DHCP, BootP, PPoE, etc.), the subnet mask, DNS server addresses, the router address, & so on. I'm not entirely sure what Migration Assistant would do about a manually assigned IP address but in my experience it does transfer the other applicable network settings, saving the user the chore of setting them up manually.

IOW, "it just works," at least for me, & I've got several different Macs on my local network.

Besides, there are other settings involved so I suggest enabling the computer & network settings option unless you a compelling reason not to do so, like you will be using the new Mac in a completely different network environment.

Hi

Yes. Good points. If OP has locations defined with different settings for specific sites it makes sense to enable that option.

AFAIK, it makes sense even if there is just one location in the original network system preference. When I try to bypass the Setup Assistant and/or skip the network configuration part of it, I have to set up the network system preference before networking works. IOW, there is no default IPv4 configuration like say DHCP, so even if the only network location is the default "Automatic" one it is still not fully configured & the Network Setup Assistant launches automatically, unless of course I've already migrated network settings with Migration Assistant.

I will admit that it has been quite a while since I tried this & never with Snow Leopard, but I think it still applies.
