Migration MSSAS cubes towards Tabular Models

Vroon already had a legacy BI Environment on premise, which was built and still managed till this day by an external party combined with own resources. 
element61 introduced an Azure Solution with Azure Analysis Services for EHS.  Vroon was very pleased with the solution and decided to incorporate their legacy BI Cubes in there as well.
In order to get this incorporated, a conversion from SSAS Cubes to a Tabular model needed to occur.
Azure Synapse Analytics is defined as data storage for the new data warehouse.
