There is a system in PHP that was not developed by me, it uses crypt to encrypt the user’s password, thus:
$senha = crypt($senha);
With the PHP update on the server, crypt is asking for a salt when creating the password for new users.
The problem is that there are already more than 10 thousand users registered in the system without salt. If I start to include salt now, I will have problems with the login of old users because they have no salt.
What to do?
You can post the code snippet?

According to PHP documentation
salt é uma string opcional para base da encriptação. Se não fornecido, será gerado randomicamente pelo PHP cada vez que chamar esta função.– Don't Panic
