 <note tip>If you are install CzechIdM on Sql server, please follow [[tutorial:adm:mssql_database_support|this tutorial]].</note>
 CentOS8 default repository version of PostgreSQL is 10 but IdM not support that version. In our tutorial, we will install newer version 12. Moreover, we install database data into /data not /var/lib which is the default option.
