Upgrade from 6 to 7 all accounts and mails lost

Initial setup
1

I use eM Client V6 and V7 is purchased, also the .msi installer is downloaded.
During the installation there is no question about Upgrade or New. After the installation I have a complete empty eM Client, no accounts, no mails etc.

Please give some info how to do just an upgrade and keep everything

Is there really no solution for an upgrade without anything lost? I still wait for an answer

after you install version 7.
Just go to Menu>File>Import…>Import from eM Client 6.
