[MM3-users] mailman changeaddress: Address already exists; can't change

Hi,

We migrated ~100 lists from mailman2 to mailman3 (very nice!) including > 6000 distinct email addresses ("subscribers").

I would like to run the mailman changeaddress command to do a global change of email for a member that moved. But they have other subscriptions using their new email, so both the old and new address are migrated to mailman3 as distinct "members", which prevents the mailman changeaddress from making the change with error:

$ mailman changeaddress "EMAIL_1" "EMAIL_2" Usage: mailman changeaddress [OPTIONS] OLD_ADDRESS NEW_ADDRESS Try 'mailman changeaddress -h' for help.

Error: Address "EMAIL_2" already exists; can't change.

Is there a workaround?

Thanks, Joel
