Simplified steps are: - Backup all your files (site, images, configs..) - Export your database (phpMyAdmin, console, Sequel Pro..) - Setup your new environment: For LAMP: Try some day LEMP (nginx): - Send files to web server root. - Import database - Enjoy :)

This tutorial explains how to install Apache, how to install MySQL, how to change the root MySQL password, how to install PHP, and how to see what libraries are available. LAMP stack is a group of open source software used to get web servers up and running. The acronym stands for Linux, Apache ( the web server) , MySQL (the database), and PHP (the language). This tutorial is written for Ubuntu.
If you want to update in place instead of migrating to a fresh server, that's possible as well. As with any major upgrade, it's highly recommended you take a snapshot of the droplet before you begin so you can roll back if problems arise. To upgrade Ubuntu itself, run:
sudo apt-get update
sudo apt-get dist-upgrade
sudo do-release-upgrade
This command will take some time and require a reboot. When asked:
Configuration file '/etc/apache2/apache2.conf'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** apache2.conf (Y/I/N/O/D/Z) [default=N] ? n
answer "No" to preserve your current Apache configurations. Do the same when asked about PHP configuration files.
