I'm planning on moving the Fedora-20 system on my laptop to a new hard disk (500GB instead of 80GB). I've partitioned the new disk. When I copy partitions from the old disk to the new one with "cp -a" (running under a Fedora Live CD) I get a lot of messages of the form diff: a/bin/acroread: No such file or directory diff: b/bin/acroread: No such file or directory
All the messages concern symbolic links. I see in "man cp" that "cp -a" included "--no-dereference never follow symbolic links in SOURCE"
Does this mean cp is not an appropriate way to copy partitions? I thought of using dd, but the partitions are not the same size, and I was not sure if this would cause problems.
Any suggestions gratefully received.

I've used rsync to do this (you have to go through the gazillion options to get all the appropriate ones though).
You'll also have to do something like boot from a live CD in order to run grub-install (or grub2-install) to make the new disk bootable.
I'd also have expected cp -a to work. Sorry, I can't say what the problem with that is, but my next try would be rsync.

There must be a zillion ways to do this (rsync, cpio, even cp) so I'll throw in my personal favorite:
# cd /old # tar --one-file-system -cf - . | (cd /new && tar xpf -)

If your using lvm, what I typically do is add both disks to the volume group, then you can use pvmove to move your lv's to the new pv. The just vgreduce the old pv out of the vg. Then you can lvextend your lv's as you see fit from your new disk.
Of course, I /boot has to be out side of lvm, but can be copied manually. And you'll have to manually install the grub boot loader on the new disk as well.

"dd" is a much better command that "cp" for this. See the following for more info and a good background as to what is going on:
https://wiki.archlinux.org/index.php/Disk_Cloning
The sections on "Cloning a partition" and "Cloning an entire hard disk" are the bits you want. Also take a look at the bit about the MBR - useful if you want a bootable drive after the cloning if you didn't take care of it when you created the partitions on the new drive.

One issue that you may run into is that the UUID of the disks will not be the same, so without modifying the boot files, the system will not work.
Generally, I just clone the old disk to the new disk using a livecd with G4L, which I am the maintaner of, or other ones like clonezilla or G4U. That will give you the same size partitions on the new disk, but you can then use other programs like gparted or LVM utilities to use the extra space.
I recently cloned an 80G disk to a 1T disk with no issues, and since the clone process uses dd to copy the raw data, all the links and other issues are not a problem.

Use dd and resize2fs. resize2fs defaults to the size of the partition.

-a includes -P, so copying symlinks is not his problem. His problem is that the links are broken, as reported by diff.

IMHO, the best choice for these kind of tasks is using bare metal recovery with tools like Mondorescue: http://www.mondorescue.org/
You can create with it a liveCD (or a USB bootable image) of the operating system filesystems, install the OS in this manner, then recover the user data (i.e. /home) using tools like rsync (even tar!) with the appropiate options.
Once upon a time, Tony Nelson tonynelson@georgeanelson.com said:

I'm not sure what environment the OP was using to do the copy (e.g. rescue mode, live CD, etc.), but some things install relative links, which should always work, while some install fully-specified links, which won't when the FS is mounted under a different location.
For example, if you have /usr/bin/acroread as a symlink to /opt/Adobe/Reader/9/bin/acroread, but then you boot a recue mode and mount the root FS under /mnt/sysimage, the /usr/bin/acroread link will be broken.
If instead you have something like /usr/bin/Mail linked to ../../bin/mailx, it will still work.
That may be all the OP is seeing, depending on the environment used.

Thanks for your and the many other suggestions. I'm going to follow your advice and use rsync, which seems most appropriate since the I have already copied the partitions.
I'm planning on saying "rsync -auvz" (which is my usual recipe). If anyone can suggest better options I shall be glad to hear them.
You'll also have to do something like boot from a live CD in order to run grub-install (or grub2-install) to make the new disk bootable.
I did actually do that, after changing the UUID settings in fstab. But I was surprised to find that Fedora-20 Live CD (on a USB stick) did not seem to do the trick, but the Netinstall CD did the job.

For copying the OS, you will also want -HAX to correctly copy hard-linked files, access-control lists, and extended attributes. For disk-to-disk copies, drop -z (don't need to compress). -u shouldn't be needed (since you want an identical system, something newer on the target shouldn't happen, and should probably be replaced if found). If the target has possibly been altered (or files have been deleted from the source), add --delete.
I like adding -P (for --partial --progress); it gives more info during sync and won't remove any partially-copied files (not usually an issue for disk-to-disk, but useful for network transfers).
So, "rsync -aHAXvP --delete" would be my recommendation.
Also, unless you've disabled SELinux, you may need to relabel on the first boot from the copy (not sure if rsync -X will set that correctly or not; haven't checked in a while).

Anaconda LiveCD uses -pogAXtlHrDx
I'm pretty sure that's the same as -aAHXx
Realize with x that it expect to rsync each volume separately, so you don't do rsync on / and expect that it will copy things correctly to /boot on a volume separate from /var or /.

I am planning a migration from a present F20 installation to a new system--that is, a new physical box on which I will do a completely fresh installation of F20 from the KDE spin. I am prepared to re-install all applications. All I want to do is move the contents of /home. What are the best commands for doing this?

i do not know what version of 'cp' you have, but i can tell you that "cp (GNU coreutils) 8.4" does not copy directories or files that have a space in their name. which is why i use 'find|cpio' for disk and directory path coping.
to insure that i have all directories and files, i open a terminal at top of copy source and target paths and run 'ls -lR > 00-path'. then i use kwrite to open files, move to bottom of files and compare the line number to insure all has been copied.

please excuse omission, as i did fail to mention this is with CentOS release 6.5 (Final).
i had same problem with with sl5.? when i stopped using it.
tho, it could be that it is fixed in fedora and not yet in rhel.
then again, being that your directories have no files and are top of path, it copies.
and again, being that it has been awhile that i found this problem, it may be just files, as my 'chemo brain' recalls, it happened when saving web pages and then coping them elsewhere. [to many web pages are written with oos] now, when i copy web pages that have spaces in their names, i either omit space or use '-' for space.
also, from habits of early unix days, i never create directory or file names with spaces.

That is not true. cp handles files with any characters just fine (just tested on an old RHEL 4 system with coreutils-5.2.1).
I would gues you have run into shell quoting issues, but that's the standard "fun" of using special characters in filenames and Unix shells. You can't just say:
$ cp File With Spaces.txt /tmp
you have to:
$ cp "File With Space.txt" /tmp

Yes. And good chance you'll need to run dracut to rebuild all initramfs's; for sure if it's being moved to new hardware. It might tolerate same hardware, different drive and fs volume UUID, but I know that the initramfs contains references to the volume UUID so you're better off rebuilding the initramfs's.
