In the past, we had new requirements for bad password lockouts that did not
fit into pam_tally neatly. So, we created pam_tally2 to let people migrate to
the version that met requirements back in the day. Then the requirements
changed again, so we created pam_faillock. This was all to allow people to
migrate to the new requirements, which had radically different file formats.
We didn't see a reliable way to move people and just left it to the admin.

Not that you have to do it this way. But I thought I'd mention how we
navigated changes in the past. The main thing is we didn't want people
getting locked out by an incompatible change in the pam stack. (Especially
for remote logins.)

Thank you for sharing this experience, I see that similar approaches have been used in the past.
