Change pack size on existing repository

Hi guys, is it possible to change the pack size of snapshots in an existing repository ? I already tried rebuild-index --compression=max --pack-size=128 --read-all-packs
but it does not work. Has anybody an idea if it´s possible ? If yes, how ?

I already know that it´s possible to mix snapshots with different pack sizes as @MichaelEischer wrote in another post. So for future snapshots i can adapt it.

Best regards

Here is the answer:

@kapitainsky I will give it a try. It´s already running 20h for now :slight_smile:
