uninstall casper and start again

[mintzd01]

Hi guys

I am trying to migrate our casper from an old mac pro (10.5.8 running 8.31) to a new xserve (10.6.8 running 8.6)

YEsterday I think I made the mistake of installing a fresh 8.52 jss on the xserve then tried to restore a backup from the 8.31 old server. This fail every time.

I am worried that I have messed up the jss and want to remove every trace of casper and start again with a new 8.31 install so I can try restoring the backup to that.

How do I get to the stage where I have removed all traces of the jss. Do I just trash the jamfsoftware my sql database and then make a new one to run the installer on or is it more complicated.

Thanks

Dan

Did you back up your database before doing all this?
Also I suggest do this in a lab environment first. Then apply to the production environment.

installing and uninstalling JSS is just running the JSS installer really. But if you are really concern then do the complete rebuild of your 10.6.8 server. Install JSS 8.6 then restore the database.

I recently had issues upgrading from 8.21 to 8.52. I did a clean install of OS X Server, new JSS, and imported our database backup, but it failed every time. It turned out that there was something about one of the database fields that was preventing the normal update scripts that JAMF uses from running.

Manually editing this field fixed the problem - let me look back & see what I did, but in the meantime can you post something more specific about your failure?

Ah - found it!

My problem had to do with clustering being enabled - are you using clustering? If not, are you seeing the database update scripts running after import? It could be a similar problem with another field.

Recently I have updated my lab JSS server from 8.43 to 8.6 and it worked just fine.
I even downgraded to 8.43 to test it again. I did this by just running the JSS Installer. After the downgrade I restored the original backup database. All good.

But I wouldn't recommend downgrading the production JSS though. It will mess things up.

Casper's update scripts work well - except when they don't. ;)
