You should be able to check in Daedalus and the pool should have a red mark stating it will be retired soon
Also, it takes N + 1 epochs for retirement to take effect - so your pool deposit will be returned following the end of the epoch the retirement transaction was executed plus one additional epoch
Sorry @ADAfrog, just 1 last question to confirm
Can I now stop my nodes/relays in my old pool? I guess the the deposit will still be returned to my payment.addr (or stake.addr) even if I stop my nodes, right?
You can stop your nodes and still receive rewards, but if you have stake you’ll want to wait for the de-registration to take effect as one you may produce blocks, and two for the health of the network.
Is that the only way to see if a pool has been retired? I have mistakingly deregistered the pool, but didn’t go through to the transaction (I believe) as my wallet wasn’t ready. In adapools.org I see that it has been retired (If I look at the about tab page), but in Daedalus don’t see the red mark (never seen it for my pool). This was in epoch 11. I am bit worried now, should I register new one and forget about this one?
