Replace a User & Employee by another User & Employee

Hello

We have 2 different users in our Projeqtor.
One user is leaving the company and replaced by the second user.

How can we replace the first user by the second replacing him, on all the elements (even the Notes added the tickets).

Thanks for you support.

Thank you for the quick answer.
But yes in our case we use mainly ProjeQtOr for the Tickets and as the user is replaced we want to do it for all the tickets where he is Issuer, Responsible, Accountable, etc...
So I can do it but field by field "manually".

And for all the notes that were added by the previous user, if we delete the user because it leaves the company we also loose the Name of the person who put this Note, we have only a number that was probably the ID of this old user. That's why we wanted to change.

I understand it is not possible but could be interesting in a future version

Thanks for your support.
