The following sections explain in detail the process of installing the SME Server software.

{{Note box|If you have previously installed and configured a server and are reinstalling the software, please be aware that you should use the procedure described [[#Upgrading_From_A_Previous_Version|here]] in order to preserve your existing configuration and data. Simply performing a new installation will erase all previously existing user accounts, user directories, i-bay contents and web site and configuration parameters. If you have not already done so, you may - depending on the size of the data - wish to back up the contents of your server onto one of your desktop computers. You can do so easily by selecting "Backup or restore" from the server manager, as explained in chapter 10.1.||

Upgrading is somewhat more complex than a clean install on a system as settings and data from the old system need to be preserved. For this reason, we start with the Upgrade procedures.

{{Tip box|msg=The Restore from USB on first boot function (on a newly installed SME 10 server), will only utilise backups that are saved as '''smeserver.tgz''' files, which are the [[SME_Server:Documentation:Administration_Manual:Chapter6#Option 8: Perform backup to USB device|Console Backup]] to USB or the Server Manager backup to Desktop. The Server Manager "Backup to Workstation" (either to USB or network share) creates a "backupdate.dar" type filename (or multiple split parts) and cannot be used to restore using the "Restore on first boot" function, it can only be used for restores from the Server Manager. The new install must have its backup to workstation configured as per the old install.}}

{{Note box|msg=It is highly recommended that USB drives to be used for backing up '''SME 9.x''' servers prior to an upgrade to 10.n be formatted with a Linux file system. When formatting a USB to use for restore it can be type FAT or FAT32, and is preferred to be ext3 or ext4. If ext4 it should '''not''' be formatted with an OS more recent than RHEL6 for SME9; this is because ext4 has seen multiple incompatible options added with time that are not back-compatible with earlier releases. So, the simple way is to mount the USB dive to the SME 9.x server you wish to back up and format it ext 3 or 4. Ensure that is is then unmounted. The USB drive must '''not''' be mounted before running console backup or the backup will fail to find the drive.}}

* Log in as admin and Backup the '''old server''' via a [[SME_Server:Documentation:Administration_Manual:Chapter6#Option 8: Perform backup to USB device|Console Backup]] to an attached USB disk. This may take many hours, even days, if you have a lot of data on your server, depending on USB port speed, USB drive speed, and types of files being backed up, i.e. whether already compressed or not etc. Typically for 250Gb of data on your server hard drive, 2 to 4 hours. Multiple terabytes may take multiple days.

{{Tip box|You have some command Line Options that you can use to set some parameters such as LVM (activated by default), '''SME9 only''' - software Raid option (none,0,1,5,6). You can use the function keys F1 to F5 to get more information about different boot options. For SME9 only see [[Booting]]}}

After showing the boot prompt for some time SME will start the installation process automatically. By default the option to test the installation medium will be selected, and the system will then proceed to the graphical mode install. Alternatively you can select to go directly to the install, either in graphical or text mode.
