Switch stacking pre-checks - different port quantity

Cuda

Level 1

Good day all

I wanted some advice on a stacking activity, I am on the research phase. It sounds more like a experiment but work is work.

The switches with their licenses are:

The questions are:

Can they be stacked? (so far I know they need to match license, so far)

I want to take; for example; a 48port and stack it to a 24port switch, because I need more ports and the 48port is quite full.

If they can be stacked, then,

Can I stack the secondary switch (slave) without the need to reboot the primary switch (master)? a non-loss-of-connectivity situation.

I´m aware that I should be in the latest version, that these are already old EOL switches, but I´m not the one making that decision, just so everyone is aware. My job is to make them work, just that.
