data restore after an upgrade?

[Jeffrey Ross]

Looking for some suggestions and thoughts.

I am upgrading the OS on a system with older hardware that I have, it is 
currently running Fedora 16 and I'm looking to upgrade it to Fedora 23.

The system has 4 SATA 1.0 interfaces, two are are in use for the two 
removable disks in the front of the case, the other two are inside the 
case and although not impossible to access they are a little difficult 
to access.

The original system has 2 disks with multiple partitions, each partition 
is in a RAID-1 configuration, the new system has the same basic 
configuration but was built on different hardware (at a physically 
different location).  Considering that system partitions are relatively 
static I've made a copy of those in the event I forgot something that I 
need, what I'm trying to figure out is how to deal with the user 
partition (/home) since this partition is very dynamic.

My thoughts are to first boot the new disks in the old system making 
sure everything is stable then either

1) break the mirror insert one of the old disks into the system and 
mount the /home partition someplace and simply copy the files, pull the 
old disk and insert the new disk then rebuild the mirror

or

2) connect one of the old disks to the now new system via a USB to SATA 
adapter (note the machine only has usb 1.1) mount the disk and copy the 
data over.

or

3) open the system up and connect one of the old disks to one of the 
internal SATA connectors mount the disk and copy the files over.

or

4) ????

It's not a huge amount of data as I'm only looking at a little less than 
25GB of data to copy over.

If it matters the system is a dual Opteron 275 system with 16GB of ram, 
its more than sufficient for what its doing which is why I'm not looking 
to upgrade.

Thanks, Jeff

Forgive the top post, on my phone.

If /home is all you want to preserve then create a partition sufficient for
it's size. Move or copy the data, latter easier as you don't need to muck
with the current file system.

During the new build go to customize setup partitions and assign /home to
the new partion along with the standard setup of /, /tmp, etc.

I have done this and makes this super easy.  HIH.

You mention the original system and the new system here, but you say you 
aren't changing the hardware.  I'll assume that you're referring to the 
operating system and that you mean you partitioned the new hard drives 
and installed Fedora 23 on them using a separate computer.

That wouldn't be so bad given the amount of data.  If you can determine 
which USB ports are on different controllers, you could hook up both 
drives as RAID and copy faster.

Or you could put a USB 2.0 card in the computer.

Couldn't you put the drive in one of the removable slots in the front?

Even on 1.1? Haven't actually done the math for 25GB of data though.

If he's going to do this, put in USB 3.0. It is impressively faster, and if 
you're upgrading such a component, why not do it properly? It won't make your 
disc faster, but most drives are well faster than USB 2.0, provided you put 
them in an suitable enclosure.

According to my math, it could be done in around 7 hours.

Sure, I could have added "2.0 or better", but assumed that would be 
obvious.  USB 3.0 enclosures are still not that common and since it's an 
older system, 2.0 would be sufficient to get it done.
