The EOGlobalID is the same but the inserted state is captured in the EC. How hard would it be to re-create the whole set of objects to be saved in a different EC?
Hmmm.... another option, if this one fails. Thanks!
By the way, the multi-instanceness brought consequences I did not quite foresee. E.g., the application sometimes imports CSV, doing these steps:
1. keep-track-of-old-records
2. read-in-CSV-and-create-new-records
3. delete-old-records
4. save
If two instances do this at once, hilarity ensues: all the old records of the slower instance are deleted by the quicker one before the slower one gets to save -- but after it started, so it tries to delete them itself, too; thus _all_ the deletion operations of the slower instance one-by-one fail, throw an exception, make me to 'forgetObject' and try again. Great.
I must be missing something pretty obvious -- there must be a considerably better approach to this :-O
