Make sure all your data is backed up before you do it. Once you have a valid recovery partition (on a thumb drive for now), boot to it on the server you are upgrading and wipe the system through Disk Utility. Use a Lion computer to create a recovery partition using the Recovery Disk Assistant. If the server came with a Lion operating system pre-installed, skip this part.

Once you’ve got all of the important stuff backed up and know what you’re going to call the server moving forward, it’s time to install the operating system. Sudo slapconfig -getmacosxodpolicy > ~/Desktop/mytextfileĪlso, backup any certificates, custom service principals you may have installed or other service data or data data that is needed on the host, if any. Sudo slapconfig -getmasterconfig > ~/Desktop/mytextfile Scutil -get LocalHostName > ~/Desktop/mytextfile Scutil -get ComputerName > ~/Desktop/mytextfile Scutil -get HostName > ~/Desktop/mytextfile Finally, we’re also going to get the OD policies using slapconfig again.
I usually just grab that from my Server Admin Open Directory screen. Also, we’ll want that Kerberos information. For the hostname, I don’t trust the GUI of OS X (no offense to the excellent UX developers employed at Apple). For the IP address, you can take screen shots of the Network System Preference pane, or pipe the output of ifconfig to a text file. Now, check your Kerberos Realm, IP address and hostname on the server.

Then, click Archive and provide a password. From here, Click on the Choose… button for Archive in: and select a location to store the Open Directory data. Open Server Admin from /Applications/Server and then click on the Open Directory service. I trust my process, it’s worked for me for more years than I care to admit.Īrchiving Open Directory data is a pretty straight forward process.

If I have any schema extensions or other mods I’ll just sync those myself prior to promotion. Instead I clean install them and just re-promote them once my Master is back in place.
I treat Replicas differently: mostly in that I don’t treat them at all. I Archive and Restore servers as often as I reinstall, upgrade or even downgrade Open Directory Masters. That’s my process for production servers.
Actually, before I import the data, I’m going to install all of the point releases, application updates and security patches. Before I do so, I’m going to export all the data from my old server and when I’m done with the fresh, clean, loving installation, I’m going to import that data back into my server. If I’m doing an upgrade from Snow Leopard to Lion, I’m about 99.9% of the time going to do so with a clean install. I don’t believe in upgrading major operating systems for servers in place.
