Hello,

I have created a managed-b eta package in my DE.  I have uploaded it to Appexchange, but it is not publicly available - I simply have a link to install it.  I installed my app into another DE.  If I need to make updates to field definitions or code in the app (which would be done in the original DE), how do I get those updates into my second DE, which has all the data uploaded into it?  I don't want to lose the data recs.

Thanks!
