Thanks @Richard.
One unexpected prerequisite was to ensure every login (username and password) included a URL. It makes sense for autofilling. However, when we first started using a password manager, autofilling was not a thing. We just looked up the login details in the password manager and copied them into the browser fields.
In short, about half of my 400+ 1Password Login records do not include URLs. These are predominantly old logins that have not been used, or have been little used, for quite some time.
In addition, some logins are not really logins, but just password records. For example, we once had a safe. I had stored the combination as a password in a login record. I obviously missed this when I imported the records into 1Password from my previous password manager. There are other similar examples.
Then there are all the other items in 1Password, such as
- Identities (eg. Driving licence details, medicare card number etc.)
- Software licences
- Password details
- Secure notes
- Debit and credit card details
- Bank account details
- and more.
They can stay in 1Password for now. However, I need to identify a longer term solution. Many others suggest transferring these details to password protected records in Notes.
