to answer your question above, no.
the ADA aren’t in the (any) wallet, as a wallet only helps control the addresses/keys associated with those ‘seed words’.
a year old daedalus wallet would need to be reinstalled. yes. you’ll never get that ‘old’ wallet version working enough to access your ADA, as it would still need an updated and current version, even if synced.
so, the two choices remain. 1. follow rdlrt’s instructions to get a new wallet on yorio w/ a seed of 15 words, then transfer the ADA using your old 12 word phrase (this will empty the old wallet, and put all value now into those new 15 words!) … or … 2. delete daedalus, reinstall daedalus, sync, then restore that 12 word wallet.
the yorio option will only take a few minutes, but will involve a new set of words and a new wallet, while the daedalus option will require installing a new/synced version of daedalus, then restoring the wallet from your current seed words, which might take a few/many hours depending on your machine and connection.
