Migration the file and linux OS from rx1600 to rx2600

[Leon Shen]

Hi,

I am not sure anyone did this before. Basiclly is transfer all the files and linux os from rx1600 to rx2600? does anyone have Technical Documents about this or any step how to implement? since both are integrity servers and can harddisk transfer and boot up ?

Regards

no you need phisycle image
use DD to get all data from rx1600 disk
Or you can use same disk :)

Hi Leon,

you may use dd as Ivajlo said or you may use a solution that I posted on that thread some time ago.

But it's important to say that for all solutions based on system image, they will work only if the target system is "equal" to the source one, i.e., the majority of the devices and system components are the same. It's because when you install a system, the installation process detects the hardware and configures a lot of software based on it.

So, if you need to migrate to a computer that only has a more quick cpu, it may work but ...
Take care about diferences between the systems.

Dear Ivajlo Yanakiev & Xyko,

Sorry for the first msg, I think I didnt explain clear. Currently need transfer all the data and os(linux) from rx1600 to rx2600. The assumption was it could be 1 harddisk with os and data and that will be easy to plug out and plug in. what if 2 harddisks, 1 for os and 1 for data? Beside DD command method and is any other good method ? another possible assumption was transfer all the data and os from 1 x rx1600 to 2 x rx2600 with 2 hard disks, can still use DD command to do 1 by 1? Plug out the orginal source disk to the new disk and use DD command to copy all the data and OS to another harddisk under 1 system. Maybe os can do this and how about Data disk ? May i know what is the complete dd command to copy whole linux os to the new disk?

thanks alot
Leon

Hi Leon,

If I could understand your point, yes, you can attach disks from 1600 to the new 2600 but you have to have attention about two important things.

Numver 1 - The disk that has the OS must be the boot disk and both of the disk must have the same "identification" to the system (ex. sda, sdb, etc...) because the boot loader and the fstab are the one that were been used on the old system.

Number 2 - All assumptions that I have made on may first reply about hardare similarity are still valid.
