SQL Diagnostic Manager includes a limited-time trial account with every installation. Note that IDERA provides separate trial and production installers.
As the end of the trial period nears, SQL Diagnostic Manager warns you each time you start the console that your trial period is ending. At the end of this trial period, if the license is not upgraded, SQL Diagnostic Manager stops functioning.

SQL Diagnostic Manager limits the number of monitored SQL Server instances to 15 when using a trial license.

Upgrade your trial license to a full license

  1. Contact IDERA Sales to upgrade your SQL Diagnostic Manager trial license.
  2. Select Help > Manage Licenses.
  3. Enter the new license key in the New Key section and click Enter. When prompted to type or copy to replace the current key, click Yes to continue.

If after upgrading to a full license you desire to move your SQL Diagnostic Manager Repository to another instance, make sure to request a new license key from IDERA Sales as this scenario is not supported.
