We have expired or expiring SQL TDE certificates! What now?
Well, the first thing we do is not panic. Even if our TDE certificate expires it won’t cause any issues. The SQL Server will continue to work normally. Even if we restore the DB elsewhere using the expired certificate we will just get a warning that the certificate is expired.
A warning is nice, and the system still working let’s us breathe a little easier, but we know that an updated certificate is a much better thing to have. In fact, setting up a regular key rotation schedule is even better and a recommended practice.
Good information, and Chris shares scripts to make it easy.
