Scott,
 
Yes.  You can restore the EnitySet to any PersistenceManager.

Thanks, David.  So far so good.  Can I restore the EntitySet to any PersistanceManager or do I have to restore and then import?
 
What I am trying to do is store reference tables locally so that I will minimize network traffic since bandwidth and network traffic is an issue.  Once I have the tables locally I will just have to worry about the changes and that should be relatively easy to accomplish....
 
Thanks again and have a GREAT Independance Day!

You can create a new PersistenceManager.  Then use ImportEntities to import the entities from one PersistenceManager to another.
 
Here is a code snippet which copies all changed Employees from one PersistenceManager to another.
 
       mPmLegacy = new PersistenceManager(true, "Legacy");
      mPmLegacy.ImportEntities(mPM.GetEntities<Employee>(DataRowState.Modified | DataRowState.Added | DataRowState.Deleted), MergeStrategy.PreserveChanges);

I think I would like to save a subset of the cache using the SaveEntitySet(ByVal pDataRows As IEnumerable, ByVal pFileName As string) overload.  But there is no clear example I have found in the tutorials or Developers Guide to develop the pDataRows in the DevForce context.  Maybe it's there and I just haven't found it or I don't know what to look for....
 
Can you post something that might enlighten me...please.  Thanks.
