On March 1st, 2024, Microsoft retires the PowerShell AzureRM module. After this date, Microsoft will no longer support the module. However, anything that is using the module will still function, but its use will be at the customer's discretion and risk, as it will no longer be maintained or updated.
To mitigate this, Sitecore has created new Blob Storage migration scripts using Az PowerShell module.
We strongly recommended applying the new Blob Storage migration scripts to the impacted Sitecore versions:
To use the new Blob Storage migration scripts:
$websiteFolder\App_Data\Migration\Invoke-Migration.ps1
$websiteFolder\App_Data\Migration\Revert-Migration.ps1
More details on the migration scripts can be found here: https://doc.sitecore.com/xp/en/developers/103/sitecore-experience-manager/use-the-blob-migration-tool.html
