Upgrading derivative canisters

If my canister spawns a new canister by instantiating an actor class, how do I upgrade that derivative canister? It won’t necessarily be in my dfx configs. It will be out there on the network somewhere and I guess I can catalog the canister ID in my original canister. If I end up with a bunch of these and need to upgrade the actor class of that canister, how do I do that? Am I going to have to pull the list and do some command-line scripting where I have to update my .json files?


I am interested in the same problem. How are you spawning derivative canisters now?

I interested too.
Do you solve it ?
