The passphrase is a completely different set of wallets.
It’s completely different in the sense that two different 24 word seed phrases would be two different wallets.
The 24 words becomes your base and then each additional passphrase that you create after the fact is essentially a completely different set of sub wallets with different addresses.
You need your main 24 words to access the base layer and then you need to know your passphrase to get to the actual account.
So yes, you would need to move your assets to that new address and then in the future you will need to know both your main base 24 words plus your 25th word passphrase.
