Recovering data from a persistent queue page file

Is there any means by which you can reprocess data from a page file into an Elasticsearch index?

My instincts tell me not because the likelihood is that the page file will probably have a partial record at the start so without the prior pages it's not possible to 'replay' it into the target index.

We've been handed the file in isolation and been told that it was retained as part of a zero size page file investigation they performed. They've specifically used the words 'may require replay' but in i'm not convinced it's even possible to replay data held in the page file (particularly not in isolation).

If anyone has any advice or suggestions i'd be very interested to hear them.
