For new Simple DNS Plus users coming from a Microsoft DNS server with a lot of DNS zones stored in Active Directory, it used to be a lot of work to migrate these zones as there was no automated way to do this.
With the new "MsDnsExport" tool - such a collection of zones can now be exported to standard zone files with a single click, after which everything can be imported in Simple DNS Plus using the Import Wizard.
The "MsDnsExport" tool is released as open source.
For details, please see the README file at https://github.com/jhsoftware/MsDnsExport#readme
