Limitations in upgrading from OCS 2007 Eval to Release versions

Microsoft has released a document describing the upgrade proces in details and there are some interesting limitations in upgrading your Eval installations (In line with Microsofts recommendations Eval should only be used for lab deployments)!

• Evaluation to full release upgrades are only supported for the volume editions of Office Communications Server full released version.
• You cannot upgrade from the MSDN® edition or to the MSDN edition of Office Communications Server 2007 full release.
• During any particular upgrade, if you cancel the evaluation to full released version of the file installation portion of the upgrade, your server will not perform as designed.
