I had an old version of 1Password (4) that stopped being supported by Chrome. I was told to upgrade to version 7 by the 1Password folks and followed their instructions to migrate my data over. But something weird happened — somehow, my 1Password 8 on Mac has old, outdated data. Like, it's literally missing years' worth of password, but includes old one. Expired credit card numbers that I've updated, etc.
Before I upgraded, I made a copy of the 1Password.agilekeychain file just in case something bad happened. I still have this file on my Mac.
1Password wants me to try to replace the outdated vault with the data on my iPhone app (deleting whatever's in the online vault first), which is up-to-date. But I'm scared to do so in case it screws up the way it did the first time I tried with my Mac. I was hoping I could somehow just upload that .agilekeychain file / overwrite this old vault somehow.
FYI this is happening on two different Macs, one that's newer and one that's older.
Anyway, before I try these steps using my iPhone which I'm super nervous about, I figured I'd check here first in case you all have any ideas. Any help would be greatly appreciated.
