Dear Proton Team,
I just upgraded to Proton Unlimited and, like many long-time users, my main address is still stuck on an old free account.
The current manual process (support → delete free account → manually re-add the address) is painful and causes permanent data loss.
Please add a long-requested feature:
Self-service merge of a free Proton account into an existing paid account
Desired flow:

In the paid account → Settings → Identities & addresses → “Import old Proton address”
Secure authentication on the free account (password + 2FA)
The old address is automatically added as an additional address/alias in the paid plan
User choice:
– Keep all emails and folders from the old account (full merge) OR
– Only recover the address (delete free account after migration)

This would:

Drastically reduce support tickets (this is the #1 request on Reddit/Proton community)
Remove a major barrier to upgrading to paid plans
Bring Proton on par (or ahead) of competitors like Tuta and Fastmail

Thousands of us are waiting for this. It would be a game-changer.
Thank you for considering!
