# Upgrade VTE 25.02.2 (3001) → 26.04 (3367) con composer install dopo copia file.
# vteUpdater.sh copia il pacchetto ma NON esegue composer: vendor ibrido → fatal su vteSelfUpdate.
#
# Prerequisiti:
#   - Pacchetti in vte_updater/packages/vte3001-3367*.tgz (o files3367 già estratto)
#   - PHP 8.3 CLI + Apache già su 8.3 per l'istanza
#   - Esecuzione come root
#
# Uso:
#   sudo bash /var/www/html/server-ops/mypantarei/vte2604-upgrade-with-composer.sh /var/www/html/vteguzzini
