If I understand it well, I should do the following sequence.

1. Set the minimum value to be say -50
2. Do a dump
3. Do a restore with --range-check

I think if I write a small shell script, it will be done in a second or so. If
I disable the updates for that time, my RRA won't lost any data.

Thank you for your help,
