# Migrate legacy multiphp to full php-fpm backend
#
# nginx+fpm (default)
#   nothing to be done here,
#   (Adding new php backends will make them available on edit/web)
#
# nginx+multiphp,
# nginx+apache+multiphp,
# apache+multiphp:
#   Change Hestia WEB_BACKEND from null to php-fpm
#   Create backend templates ex: PHP-7_3, PHP-5_6 (in $HESTIA/data/templates/web/php-fpm/)
#   v-update-web-templates
#   Loop through all web domains
#   If official multiphp tpl is used ex: PHP-72, then change backend tpl and set app web template to default
#       ( old default.tpl backend maps to PHP-7_3 )
#   If not, parse php version from tpl file , fallback to latest version,
#   Copy all non-official tpls to php-fpm folder (as app web template includin bash script if present)
#
# a2 (non-fpm) or nginx+a2(non-fpm)
# - Skipped
