Error:
Error importing database: Could not read schema model header information from package. The model version '3.6' is not supported.
In order to fix this issue, you need to download and install the latest Data Tier Application Framework(18.2).
(Here is the link: https://www.microsoft.com/en-us/download/confirmation.aspx?id=58207)
After installed the latest Framework, open command prompt as administrator and write the below command:
C:\Program Files\Microsoft SQL Server\150\DAC\bin>SqlPackage.exe /Action:import /Sourcefile:"C:\temp\UATDataBasebackup.bacpac" /tsn:localhost /tdn:AxDB_New /p:CommandTimeout="0"
It worked.
