I think I'm blind. I just don't see any model/maker in eklebanows posts...
A sandy bridge code would however run on haswell, yeah.

Had to google those models and got iX-NUMBER models. Googled them for code names (IIRC they were on wikipedia).
Yeah a direct answer would have been nice, but Lenovo themselves downplay the CPU Id but are explicit about the wifi and video models!

EDIT:
If it's true that the new machine can run the old machines instructions, then they can be cloned over a LAN as I described above with two boot cds. Almost any Linux will do, but the old systemrecuecd or sabayonino's systemrescuedvd are probably best.
I was working on an update of the last Gentoo based systemrescucd, updating all the e-builds and switching palemoon-bin for firefox, compiling generic so it can actually run on anything.
I had it all built in December just before Christmas but now I have to update it again. After spending two weekends in a row wrestling with python updates, I'm not anxious to go back. I syill had to make the CD and test. If I ever finish it I will make it available on github. I do have an account. Unlike someone else on this board that does not want to publish source. As if anyone with a brain would run closed source software from a total stranger except a recognized commercial company.

@tony: where's the different CPUs?
I don't see a reply from the OP yet....


A bit of googling says he is moving from a Sandy Bridge to a Haswell. Will Sandy Bridge code run on a Haswell? I confess that I don't know. My last Intel was a 486DX-100

I missed that part, as I got into writing mode about transferring the file - thanks for highlighting that.

So as I can guess, he'll be fine with the stage archive, which is also a good thing to have lying around for a recovery case.
I'm curious about the guy not willing to publish source, as I find that is what makes the system different from other OSes and programs.
Can you PN me some context on that?

To make the story complete....Dr Wulsen's instructions for cloning the disk to my new system worked perfectly.!!!!

I have several thoughts on the experience:
1. First and foremost Dr Wulsen you are obviously a teacher. I thank you for your patience and help. There is no way I would have successfully clone the disc and did the new gentoo install without your help. I am a computer noob but also a bright guy,
(Two medical doctorate degrees). Ás a noob it is so refreshing to have this thread rather than the usual RTFM.

2. I had a number of problems along the way including:

A. The first attempt I made to prepare the tarball exceeded the 32gb capacity of the USB stick I had. So I pruned away some old
large files and I used pbzip2 compression

B. The t440p Thinkpad had a uefi bios.... On my first attempt to partition the SSD of the new drive I did not realize this. This forced me to use parted instead of fdisk and I had to do a lot of googling to figure out how to proceed. My first two restarts booted with no grub. I got some help with that issue on the gentoo off site

C,. I had problems conceptualizing mount points when I was trying to unpack the tarball. It's not as simple as it would seem..I had one USB with the minimal installation media and another with the 16gb tar file. With the partition scheme and the different have I messed up and did not initially install the backup to the SSD. Twice I installed it to the other USB. Then I got messages that no more unpacking could occur because the disk was full.

D When I finally got the grub config right for the UEFI and rebooted the the now cloned system.... After about ten hours of work.... It took me another hour to figure out why the sounds was not working

In short....I learned a ton by this experience and by the posts on this thread.

Reading today's posts I guess I am fortunate that the two laptops were pretty similar. Just one generation difference in the processors.

Again to those of you who take the time to help newcomers like me who are eager and willing to put the time in to figure things out but need some guidance at times....I repeat my Thank You!

I guess we can mark this solved!!

Don't forget that some filesystems got utilities to copy (contents only) or clone partitions from place to place.

In some situations it simplifies the task as it pipes from A to B without insane regex.
