I am in the testing phase of using SCM 3.0 to create exports for importing into SCCM 2012. I did an import into SCCM and it ran against a few machines. I deleted the items as I was testing one other thing and when I went to reimport them I get an error about general failure storage content. I researched and I only found answers from SCCM 2007 and how to speed up the process to clean the database of the old configuration items before being able to recreate them. The site task to do it was delete aged configuration management data. I can't seem to find that task in 2012. Is there a different task in 2012 that will clear out the configuration items from the database?

Yes, I know this is an old post, Im clean them up.

Did you figure this out, if so how?
