If just change the device, the seed phrase has checksum som if device accepts it. No need to verify everything. But if you create new seed phrase with the new device, you have to verify the backup of the seed phrase is correct. Generate new seed phrase -> enter it in device. Generate public address and send some small amount. Reset the device and recover from seed phrase, if the send satoshis are there. You are good to go. After that make many copies or seed phrase and distribute them to different geographical locations.

I see. So if I’m combining two devices (Device A and Device B) since B already has a seed, I cannot just recover sats from A into B, I would need to send sats from A to B. However, if I never set up B, I could setup and just recover using the A seed phrase on a nee device, but then any other sats would need to be sent to B. That makes sense - thank you!

"since B already has a seed" - Confirm you have set the seed on your own, please. "I cannot just recover sats from A into B" - if wallet B is still empty (zero sats) you can factory reset the device and restore wallet A seed words in it. "However, if I never set up B, I could setup and just recover using the A seed phrase on a nee device, but then any other sats would need to be sent to B" - in that case, device A & device B are showing the same wallet. Both devices will receive the sats, sent to one of the addresses. It works similar to your email. You can send/read/write emails on your phone or laptop, using the same email address. The main question is: why are you changing the devices? If it's because you don't trust the wallet A, restoring the wallet in device B doesn't make sense. It's always much more secure to always generate new keys (seed words).
