.SYNOPSIS

Deploys a model.bim file to a server

.DESCRIPTION

Adds a file name extension to a supplied name.
Takes any strings for the file name or extension.

.PARAMETER serverName
The name of the SSAS server which is the deployment target

.PARAMETER databaseName
The name to give to the database we are deploying

.PARAMETER pathToBimFile
The full path the model.bim file

.INPUTS

None. You cannot pipe objects to Add-Extension.

.OUTPUTS

None

.EXAMPLE
The following example will deploy "c:\temp\model.bim" to the localhost\tab17 server
as a database called "Test"

C:\PS>.\deploy-bimfile.ps1 "localhost\tab17" "Test" "c:\temp\model.bim"

#>

## check if the path to the .bim file exists
if (-not (test-path $pathToBimFile)) {
    write-error "Could not find the bim file: $pathToBimFile"
    exit 1
}

## Load AMO Library
[Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices") > $null

## Connect to Server
$server = New-Object Microsoft.AnalysisServices.Server
$server.connect($serverName)

$json = Get-Content $pathToBimFile -Raw 

$db = [Microsoft.AnalysisServices.JsonSerializer]::DeserializeDatabase($json)

$db.Name = $databaseName
$db.ID = $databaseName

####
## at this point we have a Database object and we can alter 
## any properties such as data source connection strings
## before generating the final createOrReplace script
####

$script = [Microsoft.AnalysisServices.Tabular.JsonScripter]::ScriptCreateOrReplace($db)

$server.Execute($script)

$server.Disconnect()

Hello @dgosbell,
Thank you for your script!
I am trying to run it for PowerBI SSAS model and I gen an error:
Unable to find type [Microsoft.AnalysisServices.JsonSerializer].

Could you help to resolve it? I can't find a simple answer online.

@Kazanskyi - that probably means you have an older version of the client libraries installed on your machine. The simplest fix would be to install the most recent version by down loading the AMO installer from here https://docs.microsoft.com/en-us/analysis-services/client-libraries?view=asallproducts-allversions

Thanks @dgosbell . Works well!
