Hi Lisandro da Silva,
Thank you for your post. If you want all your old data intact then you need to upgrade your old Desktop Central Server setup from 92027 to 100079 build and then perform the migration to New Server machine. Otherwise, it will be fresh installation running on 100079 and you need to reinstall the Agents on all the client machines.
Regarding DB migration, by default it comes with PgSQL - PostGres DB. However, you can migrate to MS-SQL DB.
Refer below article: https://www.manageengine.com/products/desktop-central/using-mssql-database-how-to.html
Let me know if you need further assistance.
Regards,
