[WIP] This lab is currently in preparation

Summary of Lab

This lab is based on following PowerShell Example:

https://github.com/Azure/azure-docs-powershell-samples/tree/master/azure-migrate/migrate-at-scale-with-site-recovery

Playbook 00 - Prerequisites

This playbook will install following prereqisites:

• Ensure that the Site Recovery vault is created in your Azure subscription
• Ensure that the Configuration Server and Process Server are installed in the source environment and the vault is able to discover the environment
• Ensure that a Replication Policy is created and associated with the Configuration Server
• Ensure that you have added the VM admin account to the config server (that will be used to replicate the on-prem VMs)
• Ensure that the target artefacts in Azure are created
  • Target Resource Group
  • Target Storage Account (and its Resource Group) - Create a premium storage account if you plan to migrate to premium disks
  • Target Cache Storage Account (and its Resource Group) - Create a standard storage account in the same region as the vault
  • Target Virtual Network for failover (and its Resource Group)
  • Target Subnet
  • Target Virtual Network for Test failover (and its Resource Group)
  • Availability Set (if needed)
  • Target Network Security Group and its Resource Group
• Ensure that you have decided on the properties of the target VM
  • Target VM name
  • Target VM size in Azure (can be decided using Azure Migrate assessment)
  • Private IP Address of the primary NIC in the VM

Playbook 01 - Create Custom Image

01_start_migration.yml

Enable replication for all the VMs listed in the csv, the script creates a CSV output with the job details for each VM

Playbook 02 - Check the status of replication

02_asr_replicationstatus.yml | Check the status of replication, the script creates a csv with the status for each VM

Playbook 03 - Update Target Properties

03_asr_updateproperties.yml

Once the VMs are replicated/protected, use this script to update the target properties of the VM (Compute and Network properties)

Playbook 04 - Verify if Properties Updated

04_asr_propertiescheck.yml | Verify if the properties are appropriately updated

Playbook 05 - Start the test failover

05_asr_testmigration.yml | Start the test failover of the VMs listed in the csv, the script creates a CSV output with the job details for each VM

Playbook 06 - Clean Up Failed-over VMs

06_asr_cleanuptestmigration.yml | Once you manually validate the VMs that were test failed-over, you can use this script to clean up the test failover VMs

Playbook 07 - Perform Unplanned Failover

07_asr_migration.yml | Perform an unplanned failover for the VMs listed in the csv, the script creates a CSV output with the job details for each VM. The script does not shutdown the on-prem VMs before triggering the failover, for application consistency, it is recommended that you manually shut down the VMs before executing the script.

Playbook 08 - Complete Migration

08_asr_completemigration.yml

Perform the commit operation on the VMs and delete the ASR entities

Playbook 09 - Post Migration

09_asr_postmigration.yml

If you plan to assign network security groups to the NICs post-failover, you can use this script to do that. It assigns a NSG to any one NIC in the target VM.
