PC-BSD® makes it easy to upgrade from an earlier version of 9.x (including beta and RC versions) to the latest version of PC-BSD®. When the upgrade is finished, simply reboot to access the new version of your PC-BSD® operating system. The upgrade can be performed using [[Update Manager | the graphical Update Manager]] or from the command line.
+
'''pc-updatemanager''' is the command line equivalent to {{local|link=Update Manager}}. It can be used to apply system updates and to perform an operating system upgrade. It can also be used to update packages, providing a command line equivalent to the "Package Updates" tab of {{local|link=Package_Manager|anchor=Update_Installed_Packages|Package Manager}}.

Before attempting an upgrade, be aware of the following caveats:

<!--T:38-->
* the temporary files used by the upgrade process require 2GB of free space in ''/usr/''. If you receive an error message indicating that you do not have enough free space to perform the upgrade, you will need to delete some files or move them elsewhere in order to create enough free space.

The upgrade process will also merge any customizations you have made into the new versions of the following files: ''boot/loader.conf'', ''/etc/rc.conf'', and ''/etc/sysctl.conf.''

To start [[Update Manager]], make sure that your Internet connection is active and go to ''[[Control Panel]]'' ➜ ''[[Update Manager]]'' or type '''pc-su pc-updategui''' from a terminal. After inputting the administrative password, Update Manager will look for updates and inform you if a newer version of the operating system is available. In the example shown in Figure 5.4a, the current operating system is 9.0 and Update Manager is indicating that the upgrade to 9.1 is available.
+
While the output has been snipped from this example, the update process will download the latest versions of the packages which need updating, displaying the download progress for each file. Once the downloads are complete, it will display the reinstallation process for each file. The last step of the update process is to extract the desktop (or server) overlay and then to return the prompt.

How long the package upgrade takes depends upon the number of packages and the speed of the Internet connection. If you run this command on a desktop, you should log out and log in again so that you load the latest version of the desktop and its applications. If you run this command on a server while running the tcsh shell, type '''rehash''' in order to tell the shell that new applications have been installed.

===Applying System Updates=== <!--T:34-->
  
<!--T:14-->
+
<!--T:35-->
To perform the upgrade, check the box for the "System Upgrade" entry and click the "Install selected updates" button. A progress bar will indicate:
+
To determine if any system updates are available, type the following command as the superuser:  
 
+
<!--T:15-->

+
 
+
<!--T:16-->
+
* the download status of the software packages that are installed with the operating system and which have newer available versions
+
 
+
<!--T:17-->
+
How long these downloads take depends upon the speed of your network connection: for example, it can take an hour or so over a DSL connection. You can continue to use your PC-BSD® system while Update Manager downloads the files it needs to ''/usr/local/tmp/''.
+
 
+
<!--T:18-->
+
Once the downloads are finished, a pop-up message will indicate that the system is now ready to reboot in order to finish the upgrade. PC-BSD® will not automatically reboot the system, giving you the opportunity to close any applications that you have open before you reboot the system yourself.
+

pc-updatemanager is the command line equivalent to Update Manager. It can be used to apply system updates and to perform an operating system upgrade. It can also be used to update packages, providing a command line equivalent to the "Package Updates" tab of Package Manager.

If you type pc-updatemanager, it will show its available options:

pc-updatemanager                                                                

/usr/local/bin/pc-updatemanager - Usage ----   branches - List available system branches   chbranch <tag> - Change to new system branch   check - Check for system updates   install <tag>,<tag2> - Install system updates   pkgcheck - Check for updates to packages

  pkgupdate - Install packages updates

[edit] Upgrading Packages

To determine if newer versions of packages are available, type the following command as the superuser.

pc-updatemanager pkgcheck                                                       

  Updating repository catalogue   Upgrades have been requested for the following 253 packages:   list of packages snipped   The upgrade will require 70 MB more space   439 MB to be downloaded

  To start the upgrade run "/usr/local/bin/pc-updatemanager pkgupdate"

In this example, newer versions are available for 253 packages. The list of package names was snipped from the sample output. If no updates were available, the output would have instead said "All packages are up to date!".

If updates are available, you can install them with this command:

pc-updatemanager pkgupdate                                                      

  Updating repository catalogue   snip downloading and reinstalling output   [253/253] Upgrading pcbsd-base from 1374071964 to 1378408836... done

  Extracting desktop overlay data...DONE

While the output has been snipped from this example, the update process will download the latest versions of the packages which need updating, displaying the download progress for each file. Once the downloads are complete, it will display the reinstallation process for each file. The last step of the update process is to extract the desktop (or server) overlay and then to return the prompt.

How long the package upgrade takes depends upon the number of packages and the speed of the Internet connection. If you run this command on a desktop, you should log out and log in again so that you load the latest version of the desktop and its applications. If you run this command on a server while running the tcsh shell, type rehash in order to tell the shell that new applications have been installed.
