Content Source Creation using PowerShell

Hi,

In the migration process, we have a requirement i.e.  

1)To create content source through Power Shell

2)Updating the newly created content source with site collection through Power Shell

3)Running the full crawl on the newly created content source

For these we have achieved by writing the script as below

// CreateContentWithMulURLs.ps1

#Set the Microsoft.SharePoint.PowerShell cmdlets

$ver = $host | select version

if ($ver.Version.Major -gt 1) {$host.Runspace.ThreadOptions = "ReuseThread"}

if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null)

    {

        Add-PSSnapin "Microsoft.SharePoint.PowerShell"

    }

#Get the current script execution directory

$executingScriptDirectory = Split-Path -Path $MyInvocation.MyCommand.Definition

$InputFileName = "Content.csv"

$ContentFile = $executingScriptDirectory +"\"+ $InputFileName

$CreateContentcsv = import-csv $ContentFile

$OutputLogFileName= "Log.txt"

#Get the Log file ready

$LogDirectory=$executingScriptDirectory + "\" + $OutputLogFileName

$file = New-Item $LogDirectory -type file -force

foreach($field in $CreateContentcsv) 

{

                $SearchServiceApplicationName = $field.SearchServiceApplicationName

                $ContentSourceName = $field.ContentSourceName

                $defaultContentSourceName = $field.defaultContentSourceName

                $SiteUrl = $field.SiteUrl

}

#Remove Urls from default Content Source

try

{

    $defaultContentSource = Get-SPEnterpriseSearchCrawlContentSource -Identity $defaultContentSourceName -SearchApplication $SearchServiceApplicationName

    if($defaultContentSource.CrawlState -eq "Idle")

    {

        #If multiple addresses, remove one by one

        if($SiteUrl.Contains(","))

        {     

                        [array]$StartAddresses = $SiteUrl.Split(",")

        }

        else

        {

                        [array]$StartAddresses = $SiteUrl

        }

        if($StartAddresses.Count -ne 0)

        {

            for ($i = 0; $i -lt $StartAddresses.length; $i++)

                        {

                                        if ($defaultContentSource.StartAddresses.Exists($StartAddresses[$i]))

                                        {

                                                    $defaultContentSource.StartAddresses.Remove($StartAddresses[$i])

                                                        $LogString= $StartAddresses[$i] +" is removed from content source "+ $defaultContentSource.Name

                    add-content $file $LogString

                                        }

                                        $defaultContentSource.Update()                   

                        }

        }

    }

    else

    {

        Write-Host "$defaultContentSourceName content source is not in Idle Status. Please re-run the script later..."

        $LogString= $defaultContentSourceName + " content source is not in Idle Status. Please re-run the script later...."

        add-content $file $LogString

                Pause

        break       

    }

}

catch
