Thanks Joshua;
When I said "consolidated" I mean that if the users have reconciled and posted their data in the default version of the geodatabase?.
I need to compress all geodatabase.
I can not compress the geodatabase if all users have not reconciled and posted their data in the default version of the geodatabase, because there are an esri recommendation about it:
"To maintain good performance in a geodatabase containing versions, there are a few key administrative tasks that should be run regularly. A recommended workflow for administrators is to frequently reconcile and post, compress the geodatabase, then run the Analyze Datasets and Rebuild Indexes geoprocessing tools. This sort of routine maintenance can be set up to run nightly as a script or by building a model."

I understand that it is better reconciled and posted before that do the database compress, etc
