The classic deployment model
Let’s talk
a bit about what came before Resource Manager. These resources are now referred
to as classic. For example, you can have storage accounts, virtual
machines, and virtual networks that use the classic deployment model. The
classic and Resource Manager models are not compatible with each other. The
classic resources cannot be seen by the Resource Manager resources, and vice
versa. For example, the PaaS Cloud Services feature of Azure is a classic
feature, so you can only use it with storage accounts that are classic storage
accounts. The exception to that rule is that you can use classic storage
accounts to host Resource Manager VMs. This will make it easier to migrate your
VMs from the classic deployment model to the Resource Manager deployment model.
Note that
this means you may log into the classic Azure portal and see classic resources
but not see Resource Manager resources, and vice versa.
Note There are two versions of the
portal. The production portal is the Azure portal at https://portal.azure.com.
Most features have been moved to the Azure portal, with some exceptions such as
Azure Active Directory (Azure AD). The previous portal is called the classic
Azure portal (https://manage.windowsazure.com), and it can still be used to
manage Azure AD and to configure and scale classic resources such as Cloud
Services.
You can
migrate your assets from the classic to the Resource Manager deployment model.
For storage accounts, you can use AzCopy to copy blobs, files, and tables to a
new Resource Manager storage account. Note that tables must be exported from
the classic account and then imported into the Resource Manager account.
For virtual machines, you can shut them down and copy their VHD file to a new
Resource Manager storage account and then use the VHD file to re-create the VM.
For virtual networks, you can re-create them as Resource Manager VNets.
There is
also a migration service that is in public preview. Microsoft recommends using
this only for nonproduction workloads at this time. For more information, check
