Email domain migrated, how to retrieve data of previous account?

[Ranmalit 0]

When registration email is changing domain name, there is no way to obtain previous account data as user name and password are not recognized. 

Password recovery is also not possible as it states that operation fails.

Alias with previous domain name is present at account, however google doesn't use that email address for authentication anymore. 

Is it possible to retrieve lost notes somehow as I have parts of the books I'm writing located there
