Our cloud product has been transferred to another company. This company have their own Azure subscription and I need to transfer all the services to the new subscription. The cloud service includes an Azure SQL Database, a Cloud Service (classic, with 1 web role and 1 worker role), a storage account (classic) and VM (classic) running SQL Server with Reporting Services.
Our CI/CD server has been configured to deploy the database and cloud services. The storage service is being transferred using AzCopy.
The problem I have is, I don't have the details to reconfigure a Reporting Server. I have taken a copy of the VHDs (whilst the machine was switched off, but not sysprepped) and copied them to the new storage service. I need to find a way to create a new classic VM and attach the two VHDs to it without disrupting the existing environment. Once the environment has passed testing, the current environment will be torn down. Because the VM is a "classic" model, the Azure portal will not transfer it to another subscription. I'd like to avoid sysprepping the current live reporting server if possible because I cannot afford to disrupt the current service.
I have read a lot on here but most of it seems to apply to later (non-classic) VMs and refers to "managed" and "unmanaged" disks, which I don't understand. There are scripts that create virtual networks, etc. that the current environment does not seem to have anything comparable.
I'm hoping someone can help me with the easiest way to transfer this VM?
