I have a publication which has multiple component and pages published.
I have a requirement to delete this publication. Is there any way I can delete this without un-publishing the component and pages?
We are using Tridion 2013 SP1.
There are following two possible ways out there with 2013 SP1; you can analyze which suits you best:(Assuming you have remove any Blueprinting related dependency already)
Right-Click -> Publishing -> UnPublish. This will un-publish everything that was published from this publication to whatever targets you configured to use it.
PublishEngine.DecommissionPublicationTarget and the Core Service API with the method
DecommissionPublicationTarget. This will let you delete a publication even in case there are any issues with the un-publishing.
