If I try 1P 8, can I roll back to 1P 7 if there are issues?

A related question. Can I upgrade one of our Macs to 1Password 8, but leave 1Password 7 on our other Macs? We have a 1Password family plan with a custom shared vault, the default shared vault, and, for each family member, a number of private vaults. Judging from the response by 1P_Dave , it appears that Mac 7 and 8 use the same database, and that Mac 8 does not make changes that can’t be read by Mac 7. But it would be good to know the official answer.

In response to @jdonels , my guess is that 1Password 8 cannot use an iCloud Drive vault; a 1Password.com subscription is necessary. Once you migrate your iCloud data to a subscription, you can switch between 7 and 8. But let’s see what the support team says. By the way, be sure to look up the instructions for deleting the 1Password data in iCloud.

For what it’s worth, I used to use an iCloud vault, but migrated to a subscription. The speed and reliability of interacting with 1Password.com is much better than what I experienced with iCloud.
