Upgrade from 10.1?

I’ve been running 10.1 on 3 systems since about the time it came out and have not had any issues. But there are a couple of applications I want to move to now but can not due to all the dependencies. So now I’m looking at moving to the latest version, 11.3.

Fortunately, I think I can update each system individually and can then test existing LAMP applications before moving all the systems to the new version. So I’m not too worried about anything we’ve built in house.

What kind of problems can I expect to have in just going to the new software? Any “gotcha’s” that others have run into that I should be looking for?

TIA,

You really need to fresh install, upgrade will almost certainly be a disaster. Though there are those who will try and convince you otherwise!
Backup
Format to ext4 from whatever you have
Fresh install.

Difficult to say. It is possible to do the upgrade, but upgrades have their
own set of difficulties if you are not experienced. I would certainly try
it (via dvd, or network, not online (dup)).

I don’t remember all the issues. Have a look here

http://doc.opensuse.org/products/opensuse/openSUSE/opensuse-reference/cha.update.html#sec.update.version
(14.2, software changes)

(Time ago this doc section was more complete)

and look for the changes in all intermediate versions. The most important
one I can remember is the changes from the /dev/hda, hdb, etc scheme to
/dev/sda, sdb, sdc, etc. In order for the upgrade to work you have to adapt
fstab in advance.

As a previous step, I would install the target version in a test partition
of the same machine, and test it a bit. If it works, then do a full backup
of the original setup, and proceed with the upgrade. If it fails
completely, you have the backup, so you can try again, or install fresh.

You can, of course, break the upgrade in steps. Go first to 10.3, then to
11.2, perhaps. 11.3 is different (video). You have the test partition I
told you about that will help you to set video in the same manner.

Add a vote for trialling the migration on a spare system (perhaps your desktop even) and also checking hardware support via install into test partition. There are good performance reasons to migrate rather than upgrade, 10.1 is likely using ReiserFS with weaker support, Novell moved to ext3 long while ago (10.3), and now we have ext4 with improvements like extents.

If your machines have access to, or serve the internet, then either stay more current in future or paying for a commercial grade supported system with longer maintenance like SLES.
