Every certificate has a validity period. After the end of the validity period, the certificate is no longer considered an acceptable or usable credential. CAs cannot issue certificates that are valid beyond their own validity period. A best practice is to renew the CA certificate when half of its validity period is expired. When installing a CA, you should plan this date and ensure that it is recorded as a future task.
As in many databases, the certification authority's database is a file on the hard drive. In addition to this file, other files serve as the transaction logs, and they receive all modifications to the database before the changes are made. Because these files may be accessed frequently and simultaneously, it is best to keep the database and transaction logs on separate hard drives or high-performance disk configurations, such as striped volumes.
The location of the certificate database and log files are kept in the following registry location:. You can move the certificate database and log files after installation.
