I want to move an entire array of drives from old server hardware to new server hardware. There are 3 SATA drives with two partitions each; a small boot partition and a data partition. There are two software RAID 1 arrays, one containing all the boot partitions and one containing all the data partitions.
My understanding of software RAID is that all of the information is stored on the drives, so neither the hardware nor the software (OS) will see anything different if I plug them into another motherboard, even if they're not on the same ports. I guess I might need to make sure I boot off the same physical drive as I do now, but even the boot partition is mirrored so perhaps not?
Can I take this array of drives and plug them into a replacement server and just boot it? The new server does not have exactly the same hardware but the overall configuration is the same; they both have 64-bit Intel CPUs and a similar amount of RAM.
This question is not the same as How do I move a Linux software RAID to a new machine? because in my case the kernel is in the RAID array, so everything will be moved together.
