Can GlobalID Change?

[ApurvaGoyal]

We have a mobile application where we are using GUIDs to uniquely identify a feature for users to edit in field. However we do also have some legacy data in mobile cache which doesnt have the GUIDs populated. This Unique identifier will also be used outside of SDE to associate a feature to its SSF file.

In this case can we use ESRI's GlobalID instead of our GUID column? Can any edit operation change a GlobalID field value for a feature?

Any information on this will be very helpful.

Thanks

I think yes. We have table in system which can be populated by different sources, not just esri. Mobile device reads that data. When data inserted by not esri we just create GlobalID from sequence. When new record inserted new GlobalID is created by framework. I did not try to change it on device.
