My home server is on aging hardware and is due for an upgrade. I've purchased a new CPU, memory, mobo, etc. and plan on doing the upgrade this weekend. I plan on keeping my hard drives and moving the existing installation to the new hardware. From what I can tell this should be a mostly seamless transition. Both the old and new CPU are x86_64. Both the old and new video cards are RADEON, so I shouldn't even need to install a new video driver.
I am wondering if there are any things that I may not be considering that might cause issues with the transition. I had planned on keeping the hard drive order the same, but is this actually necessary? There are four disks, with the 1st and 2nd partition in each being RAID1 for /boot and swap space, respectively. The third partition on each disk makes up a large RAID5 LVM volume group where the rest of the partitions are located. Looking at /proc/mdstat, the physical disks definitely appear to have an order, as evidenced by the offsets after them:
Personalities : [raid1] [raid6] [raid5] [raid4]
md1 : active raid1 sda1[0] sdb1[1] sdc1[2] sdd1[3]
96344 blocks super 1.0 [4/4] [UUUU]
md0 : active raid5 sda3[0] sdb3[1] sdc3[2] sdd3[4]
5847062016 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/4] [UUUU]
md2 : active raid1 sda2[0] sdb2[1] sdd2[3] sdc2[2]
4393664 blocks [4/4] [UUUU]
unused devices: <none>Anyway, just wondering if theres anything I should watch out for, as I've never attempted a move like this before. Any input would be much appreciated. Thanks!
