![]() Other software may have similar restrictions. It is against the license agreement to move an OEM copy of Windows. Activation: All software, including Windows, that tracks licensing by hardware signatures will be triggered by P2V.MSDN has an article explaining how to view and remove devices that are no longer present (make certain that you perform the steps regarding the DEVMGR_SHOW_NONPRESENT_DEVICES environment variable. Do not be surprised if you encounter IRQL_NOT_LESS_OR_EQUAL errors after a P2V these are hardware-related. Some manufacturer removal routines are less than thorough. Windows will hide drivers for which it can’t find matching hardware. Phantom drivers: Completely removing old driver packs and supporting software might prove to be difficult.Unfortunately, these errors are commonly insurmountable, although you might be able to use the Windows repair options from the installation media. Often, after a P2V, you will encounter 0x0000007b stop errors, which essentially mean that the boot loader could not find the startup files. Versions prior to 2008 commonly failed when transitioning from SCSI to IDE or vice versa. Hard drives: Windows has never transitioned well from RAID to non-RAID environments.These are the things that you can expect to have trouble with after a P2V: Wherever possible, always choose a data migration path over a physical-to-virtual conversion. Whatever your application is, start with your favorite Internet search engine or the application’s support team and research migrating from one server to another. I am tempted to include Internet Information Services (IIS) in the list of “never migrate” just because moving IIS is usually very simple as well, but many of my earliest P2V experiences were with IIS and those ended well. If you want to continue using the same IP address and name of the original domain controller, then perform the migration twice, with the second migration using the original name and IP.Ĭonverting Exchange is more or less the same operation: add the new server into the Exchange infrastructure and remove the old one. Decommission the old domain controller.Remove the old domain controller from Active Directory Sites and Services.Use a DHCP failover scope to transition DHCP services from old to new. Even the article’s title includes the text “Level 100”. For some reason, the TechNet article that describes how to promote a new domain controller makes this process look extremely difficult, but it isn’t. Promote the new system to be a domain controller.Build a new Windows Server operating system environment.Migrating Active Directory Domain Servers is preferred to a P2V operation just because moving domain services is ridiculously simple: Systems that rely on specialized hardware, such as fax boards and licensing dongles.In particular, do not perform P2V for these systems: You might never make the thing work at all. Software support departments won’t like it. You will have a hybridized system that may not ever function optimally. You will probably spend hours making your converted system work correctly. Truthfully, the best approach is to not perform P2V at all. Good Advice: Do Not Perform P2V Conversions It is also commonly done when an organization first begins to transition from an all-physical environment to a virtual environment. It is commonly done with the intent of retiring old hardware without rebuilding the system. In simple terms, a physical-to-virtual (P2V) conversion transfers the entire state of an operating system installed on bare metal into a virtual machine. What is a Physical-to-Virtual Conversion? Whatever your situation, this article is for you. There are also many administrators inheriting systems from departed colleagues that avoided virtualization right up to the bitter end. There are still a great number of legacy systems waiting their turn to be transferred. As virtualization has become the norm, the need for physical-to-virtual conversions (P2V) has begun to decline for many of us.
