+# Easy UniFi Controller Upgrade Script for Unix/Linux Systems
+# by Steve Jenkins (stevejenkins.com)
+# Last Updated June 23, 2016
+
+# REQUIREMENTS
+# 1) Assumes you already have any version of UniFi Controller installed 
+# and running on your system
+# 2) Requires a service start/stop script to properly shut down and 
+# restart the UniFi controller before and after upgrade. I've written
+# compatible startup scrips for SysV and systemd systems at 
+# http://wp.me/p1iGgP-2wl
+# 3) Requires wget command to fetch the software from UBNT's download site 
+
+# USAGE
+# Modify the "unifi_version" variable below using the version number you
+# wish to install (e.g. "5.0.7"). For Beta versions, use the full download 
+# directory in the UBNT download link (e.g. "5.0.8-ac599f45"). Modify any 
+# of the additional variables below (defaults should work fine), then run
+# the script!
+
+# UniFi Controller version to install
+unifi_version=5.0.7
+
+# Additional variables (defaults should work fine on most systems)
+unifi_parent_dir=/opt
+unifi_dir=/opt/UniFi
+unifi_backup_dir=/opt/UniFi_bak
+unifi_archive_filename=UniFi.unix.zip
+unifi_archive_location=https://www.ubnt.com/downloads/unifi/
+temp_dir=/tmp
+
+# SHOULDN'T HAVE TO MODIFY PAST THIS POINT
+
+# Create progress dots function
+function show_dots() {
+	while ps $1 >/dev/null ; do
+	printf "."
+	sleep 1
+	done
+	printf "\n"
+}
+
+# Let's DO this!
+printf "Upgrading to UniFi Controller v$unifi_version...\n"
+
+# Stop the local UniFi Controller service
+printf "\n"
+service UniFi stop
+
+# Retrieve the updated zip archive from UBNT (overwriting any previous version)
+printf "\nDownloading $unifi_archive_filename from UBNT..."
+cd $temp_dir
+wget -qq $unifi_archive_location/$unifi_version/$unifi_archive_filename -O $unifi_archive_filename &
+show_dots $!
+
+# Remove previous backup directory (if it exists)
+if [ -d "$unifi_backup_dir" ]; then
+	printf "\nRemoving previous backup directory...\n"
+	rm -rf $unifi_backup_dir
+fi
+
+# Move existing UniFi directory to backup location
+printf "\nMoving existing UniFi Controller directory to backup location...\n"
+mv $unifi_dir $unifi_backup_dir
+
+# Extract new version
+printf "\nExtracting downloaded software..."
+unzip -qq $temp_dir/$unifi_archive_filename -d $unifi_parent_dir &
+show_dots $!
+
+# Jump into the backup directory
+cd $unifi_backup_dir
+
+# Create an archive of the existing data directory
+printf "\nBacking up existing UniFi Controller data..."
+tar zcf $temp_dir/unifi_data_bak.tar.gz data/ &
+show_dots $!
+
+# Extract the data into the new directory
+printf "\nExtracting UniFi Controller backup data to new directory..."
+tar zxf $temp_dir/unifi_data_bak.tar.gz -C $unifi_dir &
+show_dots $!
+
+# Restart the local UniFi Controller service
+printf "\n"
+service UniFi start
+
+# All done!
+printf "\nUpgrade to UniFi Controller v$unifi_version complete!\n"
