Hello, Thanks for replay. I will consider fresh reinstall to upgrade Uyuni. Current setup works very well for us without big isues so upgrade can be postponed. Have a nice weekend, Cristian Gherman On 8/2/19 8:04 PM, Julio Gonzalez wrote:

Hello, Cristian.

4.0.2RC was a development version and migrating to Stable is not supported in any way (that's why devel has a warning about that, at the website, maybe we should add other at the YaST2 installer).

Your case is even more tricker than usual as you are on openSUSE 15.0 and not openSUSE 15.1, so I am not 100% sure that the migration script that we prepared will work.

But that said, I can give you the same advice I gave to David Mace at the thread "repo issue?"

First of all: take a full backup of the server with whatever method you have available, so you can restore if there are problems.

Then:

- Take note of your current susemanager-schema version (4.0.X, let's call it current_version) (rpm -qa|grep susemanager-schema should give you that) - Apply the upgrade procedure as if you were migrating from 4.0.1 (Leap 42.3) to 4.0.2 (Leap 15.1) [1] - This will create a log at /var/log/spacewalk/schema-upgrade where you will see lines like "SQL> select 'susemanager-schema-3.2.18-to-susemanager- schema-3.2.19/002-alter-susesaltevent.sql.postgresql' from dual;" for each SQL script applied. - Take note of the susemanager-schema version installed by the update (should be 4.0.13, use the same command on the first step) - Then review /etc/sysconfig/rhn/schema-upgrade/ and verify if everything from the migration path from current_version up to 4.0.13 was applied.

If something is missing, you will need to apply it manually:

$ sudo su - postgres $ psql -f <SQL_SCRIPT> <yourdbname-usually-uyuni>

But of course, I have to repeat it: it is not supported in any way and could bring problems in the future.

So the preferred and only supported method is starting from scratch with 4.0.2 and then readding the minions.

[1] If you see errors about lines 35-38 with rpm being unable of removing packages (https://github.com/uyuni-project/uyuni/blob/master/susemanager/bin/ server-migrator.sh), that should be fine.

Hello,

First of all, I love you work. It helped me very much in last months.

I have Uyuni server on Opensuse 15.0 which used devel repos until Opensuse 15.1 switch.

I look over documentation andnot found how to upgrade OS and Uyuni whitout loose minion settings (or readd to the master).

What you suggest to do:

a) Clean install and reattach minions to the new master?

b) backup salt master config files, postgresql database, and restore on new machine, after ?

c) Upgrade OS and Uyuni whithout any changes?
