I have had a few people asking for this .. So I’m just going to share you my script that I always you to convert a Single Tenancy Demo Environment to a Multi Tenancy Demo Environment, with some (Empty) companies per Tenant and such.. .
And I’m going to make it easy on me .. there are no guarantees that it will work for you out-of-the-box 
.
The Script
#Preparing PowerShell Set-ExecutionPolicy RemoteSigned -Force Import-Module 'C:\Program Files\Microsoft Dynamics NAV\71\Service\NavAdminTool.ps1' #Parameters $ServerInstanceName = "DynamicsNAV71" #The current ServiceInstance $DatabaseServer = "localhost" #The Database Server where the database is located $Databasename = "NAV2013R2_BE" #The database that will be migrated to Multi-Tenancy $DemoCompanyName = "CRONUS BELGIË NV" #This company will be renamed to "MainCompany".

As you see, I’m usually working with a Belgian database. The “parameters” section should help you to easily change the script to your own needs.
Furtheron, I’m just going to keep 1 active company (Belgian version has 2), copy it to a PRS company, create 13 more companies and going to create multiple tenants with each tenant some companies.. . Just try it out, and see what happens .
The Result
It creates for you a Multi-Tenancy environment with three tenants:
- “MainTenant” will have 1 company, being “MainCompany”. Check With:
Get-NAVServerInstance | Get-NAVCompany -tenant “MainTenant”
- “prscompany” will have 4 companies. One with data (PRS Company). Check With:
Get-NAVServerInstance | Get-NAVCompany -tenant “prscompany”
- “waldocompany” will have 10 empty companies. Check with:
Get-NAVServerInstance | Get-NAVCompany -tenant “waldocompany”
Good luck!
