Upgrading from PHP 7 to PHP 8.x on Acquia

LA Drupal - July 2022

Why

• New version of PHP
• PHP 7 EOL November 22, 2022
• Might as well move to latest PHP 8
  • 8.1 when slides were created

Goal

• One D9 site
• Uses PHP 7.4

Local Setup

• Using Lando
  • Update Lando to use PHP 8
• Update composer
  • Change platform to update version of PHP
    • Otherwise picks up version of PHP on machine

What about Acquia?

• Acquia "supports" PHP 8.1
• However, Acquia does not have Drush 11
  • Drush 10 is not PHP 8 compatible
  • Drush 11 is PHP 8 compatible
• Upgrade is manual
  • Use their GUI

Thanks!
