<#
    .SYNOPSIS
        Generate a bacpac file from a database
         
    .DESCRIPTION
        Takes care of all the details and steps that is needed to create a valid bacpac file to move between Tier 1 (onebox or Azure hosted) and Tier 2 (MS hosted), or vice versa
         
        Supports to create a raw bacpac file without prepping. Can be used to automate backup from Tier 2 (MS hosted) environment
         
    .PARAMETER ExportModeTier1
        Switch to instruct the cmdlet that the export will be done against a classic SQL Server installation
         
    .PARAMETER ExportModeTier2
        Switch to instruct the cmdlet that the export will be done against an Azure SQL DB instance
         
    .PARAMETER DatabaseServer
        The name of the database server
         
        If on-premises or classic SQL Server, use either short name og Fully Qualified Domain Name (FQDN).
         
        If Azure use the full address to the database server, e.g. server.database.windows.net
         
    .PARAMETER DatabaseName
        The name of the database
         
    .PARAMETER SqlUser
        The login name for the SQL Server instance
         
    .PARAMETER SqlPwd
        The password for the SQL Server user.
         
    .PARAMETER BackupDirectory
        The path where to store the temporary backup file when the script needs to handle that
         
    .PARAMETER NewDatabaseName
        The name for the database the script is going to create when doing the restore process
         
    .PARAMETER BacpacFile
        The path where you want the cmdlet to store the bacpac file that will be generated
         
    .PARAMETER CustomSqlFile
        The path to a custom sql server script file that you want executed against the database
         
    .PARAMETER ExportOnly
        Switch to instruct the cmdlet to either just create a dump bacpac file or run the prepping process first
         
    .EXAMPLE
        PS C:\> New-D365Bacpac -ExportModeTier1 -BackupDirectory c:\Temp\backup\ -NewDatabaseName Testing1 -BacpacFile "C:\Temp\Bacpac\Testing1.bacpac"
         
        Will backup the "AXDB" database and restore is as "Testing1" again the localhost SQL Server.
        Will run the prepping process against the restored database.
        Will export a bacpac file to "C:\Temp\Bacpac\Testing1.bacpac".
        Will delete the restored database.
        It will use trusted connection (Windows authentication) while working against the SQL Server.
         
    .EXAMPLE
        PS C:\> New-D365Bacpac -ExportModeTier2 -DatabaseServer localhost -DatabaseName AxDB -SqlUser User123 -SqlPwd "Password123" -NewDatabaseName Testing1 -BacpacFile C:\Temp\Bacpac\Testing1.bacpac
         
        Will create a copy the db database on the dbserver1 in Azure.
        Will run the prepping process against the copy database.
        Will export a bacpac file.
        Will delete the copy database.
         
    .EXAMPLE
        PS C:\> New-D365Bacpac -ExportModeTier2 -SqlUser User123 -SqlPwd "Password123" -NewDatabaseName Testing1 -BacpacFile C:\Temp\Bacpac\Testing1.bacpac
         
        Normally used for a Tier-2 export and preparation for Tier-1 import
         
        Will create a copy of the registered D365 database on the registered D365 Azure SQL DB instance.
        Will run the prepping process against the copy database.
        Will export a bacpac file.
        Will delete the copy database.
         
         
    .EXAMPLE
        PS C:\> New-D365Bacpac -ExportModeTier2 -SqlUser User123 -SqlPwd "Password123" -NewDatabaseName Testing1 -BacpacFile C:\Temp\Bacpac\Testing1.bacpac -ExportOnly
         
        Will export a bacpac file.
        The bacpac should be able to restore back into the database without any preparing because it is coming from the environment from the beginning
         
    .NOTES
        The cmdlet supports piping and can be used in advanced scenarios. See more on github and the wiki pages.
