Sorry I don't have an answer, but I would like to second this
question. I run a small friendnet, and as we add more storage
nodes, I would like to consider changing the K-N parameters too to
save space. Thank you to anyone who may offer some guidance<br>

Assume that I have a grid with 10 servers with 3-6, and there are
already files stored. With the scale growth of the grid, maybe to
100 nodes or even 1000, is there possibility to change the K-N
parameter to a larger one (for example 20-40) without damaging the
existing files. Another assumption would only customers have the
encryption key.

<div>In other words, is that possible to have two different
settings of parameters on the same grid simultaneously. </div>

<div>If not, I think the only way is to reconstruct all existing
files before re-starting the system with a new parameter. I
need to gather the encrypted shares (with 3-6 setting),
storing them on temporary storage, and then re-distribute
files (with 20-40 setting). The question is, in such process
do I need encryption keys from customer nodes. In other words,
do I need both encryption keys and parameters to do so?</div>
