Upgrading Windows Server 2008 R2 without media

The supported upgrade paths are:

  • Windows Server 2008 R2 Standard -> Windows Server 2008 R2 Enterprise -> Windows Server 2008 R2 Datacenter
  • Windows Server 2008 R2 Standard Server Core -> Windows Server 2008 R2 Enterprise Server Core -> Windows Server 2008 R2 Datacenter Server Core
  • Windows Server 2008 R2 Foundation -> Windows Server 2008 R2 Standard

To determine the installed edition, run:

DISM /online /Get-CurrentEdition

To check the possible target editions, run:

DISM /online /Get-TargetEditions

Finally, to initiate an upgrade, run:

DISM /online /Set-Edition:EDITION_ID /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

WARNING: One important note, is that the server can’t be a DC at the time of upgrade. If you demote a DC using dcpromo, you can upgrade, then re-promote it (you may need to migrate FSMO roles, etc, in order to succesfully demote.)
