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!
Best regards,
