I want to synchronize backup of my personal data to family account

I am not good at English, so there may be some strange things.
I'm sorry.

I have individually contracted 1password up to now.

However, I decided to sign 1password with my family.
So, I canceled 1password that I had an individual contract and joined 1password newly contracted by my family.

I have backed up my personal data properly.

Here is something I do not understand.

I joined the 1password my family made a new contract.
Naturally, there is no data such as the password I used before.

I would like to synchronize the data I used to my personal safe in my family account.
However, the "Sync" button is not displayed on the 1password environment setting screen.
So, I can not add data that I used to be personal with before.

How can I add (synchronize) my previously used data to my personal safe in my family account?

The sentences may be wrong.
If there is a mysterious point please ask a question.

I'm sorry
Thank you.
