  • Choose "Compress None" and click on "Build backup".
  • Go into directory of your Dolibarr data files (directory is defined into "Setup - System information - Dolibarr - All parameters" on line "Root directory for data files").
  • Go into subdirectory admin/backup. You will find the dump of database you just build with previous step.

Create a PostGreSQL database

  • Ranme conf.php file of Dolibarr into conf.php.mysql (file should be into /etc/dolibarr or htdocs/conf)
  • Run Dolibarr. Because the conf file does not exists anymore, the install process will be suggested. Choose first installation and provide all informations of your postgresql database as data source. Run process until the end. About administrator account asked at end, choose same than the one exisitng into your MySql sessions.

sed "s/\\\'/\'\'/g" mysqldump_mydatabase_version_date.sql > mysqldump_readyforpgsql.sql

psql -h name_or_ip_of_postgresql_server -d name_database_postgresql -U login_database_mysql -f mysqldump_readyforpgsql.sql

$dolibarr_main_db_pass='password_database_mysql';
$dolibarr_main_db_type='pgsql';
