Dears Craig, Roberts, Reece and Shane Thank you very much for your thoughts. They're helpful! ;-) I've chosen the dump approach to another table in the migration server and then INSERTing the different recs with a WHERE clause for every non-existing timestamp for a deviceID.
As far as the pkey was concerned (entry_nbr) it didn't cause me any problems as what's important were the timestamps in the relevant column. Again thanks!
