How do I edit the schema of a feature service without losing data and attachments?

Discussion created by segretjp on May 15, 2013
I have a hosted feature service we are using to collect sample locations in the field with picture attachments.  We have been having problems with the automatic editor tracking and I would like to add a Sample_Date field to the service.  There are two ways I can think of to make the changes I need.

  1. Update the existing hosted feature service.

  2. Create a new feature sservice and append data and attachments

Which is the recommended workflow, and how do I accomplish the task without losing any of my existing data? I appreciate any help that anybody has to offer.
