The "Move" Misconception

Changing a Power BI tenant's home region, like moving from Singapore to Australia, is a major technical challenge. The term "moving" is misleading. The official Microsoft process, a "tenant remap," is not a migration. It's a destructive reset that deletes all data, reports, and configurations. Without a solid backup and restoration plan, you risk total data loss.

The only safe method is a parallel run migration. This guide will show you how to treat your current Singapore setup as a legacy system and build a new one in Australia, ensuring business continuity and data integrity. We'll cover modern challenges with Microsoft Fabric and provide a step-by-step blueprint for a successful migration.

Control Plane vs. Data Plane: The Core Concept

Understanding the difference between your tenant's Home Region (Control Plane) and Multi-Geo Capacities (Data Plane) is crucial. Your Home Region is the permanent "brain" of your tenant, storing all metadata, permissions, and report definitions. Multi-Geo allows you to store the actual data files in other regions, but the control plane remains anchored in the home region.

At a Glance: Remap vs. Parallel Run

Choosing the right strategy is the most important decision you'll make. This table breaks down the differences between the high-risk official remap and the recommended parallel run approach.

Migration Path Decision Tree

This decision tree will help you navigate the key questions to determine the correct migration methodology for your specific scenario.

Parallel Run Migration Methods

A parallel run involves moving content from your source (Singapore) to your target (Australia). Here are the common methods, which you can filter based on your needs.

Critical Migration Hurdles

A parallel run isn't without challenges. Here are the key technical hurdles you must plan for.

Infrastructure Dependencies

Don't forget the supporting infrastructure:

• On-Premises Data Gateways: Gateways are region-specific. You must install and configure a new gateway cluster for the Australia region.
• User Permissions: Permissions are not automatically migrated. They must be meticulously reapplied in the new environment. Scripting this with PowerShell is highly recommended.
• Application & URL Dependencies: Audit all custom apps, scripts, and bookmarks that might have hardcoded URLs or references to the old environment.

# Example: PowerShell to get workspace users (for permission backup)
# This is a conceptual snippet. You'll need the Power BI cmdlets installed.

Install-Module -Name MicrosoftPowerBIMgmt
Login-PowerBI

# Get all workspaces
$workspaces = Get-PowerBIWorkspace

# Loop through each workspace and get users
foreach ($workspace in $workspaces) {
    Write-Host "Workspace: $($workspace.Name)"
    Get-PowerBIWorkspaceUser -Workspace $workspace
}
