====== How to upgrade LiteSpeed Web Server from free version to paid version ======

Upgrade from Standard Edition (free) to Enterprise Edition (paid) involves two steps:
  * **Order a license**
  * **Download and install Enterprise Edition tarball** to replace existing install.

===Instructions:===
  - Go to [[https://store.litespeedtech.com/store/cart.php?gid=5|LiteSpeed Store]] to order license. Go to [[litespeed_wiki:licenses:choosing-a-license|this page]] to find out what license you need if you are not sure what to choose.
  - Login to your server as root (via ssh or console)
  - Download and install package
    - Get the download link from [[https://www.litespeedtech.com/products/litespeed-web-server/download|LiteSpeed Web Server download page]]. Say, you choose "**Linux (x86_64) 4.1.13 Ent**" edition for your server (platform needs to be matched), copy the [[http://www.litespeedtech.com/packages/4.0/lsws-4.1.13-ent-x86_64-linux.tar.gz|Download]] link next to it.
    - Run below commands to download and install

    cd /root
    wget http://www.litespeedtech.com/packages/4.0/lsws-4.1.13-ent-x86_64-linux.tar.gz
    tar zxf lsws-4.1.13-ent-x86_64-linux.tar.gz
    cd lsws-4.1.13
    echo "xxx-xxx-xxx" > serial.no    # where xxx-xxx-xxx is the license key string
    ./install.sh
    # Choose 'U' for upgrade when prompted and default for the rest.
