Is it technically possible to integrate CRM 2011 with NAV 2018 using the NAV build-in connector?

What I did is the following :

  • Installed the Connector for Microsoft Dynamics NAV version 3.3.1007.1 standalone application because the solution found in NAV 2018 failed to install.
  • Enabled the connector on NAV 2018
  • I tested to couple a currency on NAV and it was created on CRM

I just want to make sure that technically this is possible noting that I know it is better to upgrade the CRM but this is not applicable at this moment.

Thanks :)
