I need to take all of the customizations from one environment, and move them to another.  However, the source environment has several managed solutions which are not present in the new environment (its brand new).  If i take the entire default solution and export it, then import it to the new environment, it tells me that everything from the managed solutions is missing.

If I then go to the managed solution, create an unmanaged solution to export the individual entities, when I export and import that, it tells me that the managed solution is missing.  even if I go down to the single entity level and export just one entity and its required components, it tells me that the entity that I am importing is missing or not in the solution.  

Is there a way to move managed solution components without the original managed solution files?  I dont have them.
