Hi Evgeni,

The old and new IDs can be found in the "bitstream" table in the database
(see the "bitstream_id" and "uuid" columns for the old and new IDs
respectively).  New bitstreams will *not* receive an old ID however, which
is why the URLs now only utilize the new UUIDs.

Handles are preserved through the entire migration, as Handles are
external, persistent identifiers.  The old Bitstream IDs were internal
identifier only, and have been replaced by UUIDs going forward (as UUIDs
are universally unique, while the old ID format was simply an incremental
internal counter in the database).
