Re: [Users] Fedora upgrading from 3.1 to 3.2

Yes, progress is always good:) I would like to have some pointers about nr. 4: Restore certificates. Then I can ask one of my co-workers to test the procedure and report back. So, restore certs; How to? Or! I saw in another thread there was a "engine-cleanup --dont-drop-dbase" something or other... Is there an equivalent for "engine-setup", like "--dont-touch-dbase"? Or "engine-cleanup --dbase-something" and then "engine-setup" again, and it´ll just play nice with the dbase that´s still there perhaps? /Karli ________________________________________ Från: Alex Lourie [alourie(a)redhat.com] Skickat: den 30 juni 2013 17:29 Till: Karli Sjöberg Cc: users(a)ovirt.org Ämne: Re: [Users] Fedora upgrading from 3.1 to 3.2 Hi Karli On Wed, Jun 26, 2013 at 5:28 PM, Karli Sjöberg <Karli.Sjoberg(a)slu.se&gt; wrote: > Update! > > I have actually made some headway, I managed to get it passed the > database upgrade!

There's a pushd/popd action used in sh scripts to change working folder and then get back to the original one.

Now, if you have a working engine, that's good. Remember though that you started with clean DB. When DB has entries, the upgrade.sh run may not be as fluent as it was before. But, if it works, I guess you could use the same strategy for upgrading the complete working environment: 1. Backup DB and certificates 2. Upgrade DB in a stand-alone mode and save it aside. 3. Install 3.2, restore the engine DB from upgraded backup. 4. Restore certificates. 5. Start the engine. 6. Enjoy?
