Additional notes

If we skip this

            if (isset($this->mapAttributeIdsDestOldNew[$record['attribute_id']])) {

in line L461 we need to skip this also in L571.

Solving this problem:

            foreach ($destinationRecords as $record) {
                if (!isset($this->mapAttributeIdsDestOldNew[$record['attribute_id']])) {
                    continue;
                }
                $record['attribute_id'] = $this->mapAttributeIdsDestOldNew[$record['attribute_id']];
                $destinationRecord = $this->factory->create([
                    'document' => $destinationDocument,
                    'data' => $record
                ]);
                $recordsToSave->addRecord($destinationRecord);
            }

skipping here also:

                if (!isset($this->mapAttributeIdsDestOldNew[$record['attribute_id']])) {
                    continue;
                }
