No details are shown when you open an archived databases.
The databases from the previous versions should be upgraded.
Essentially we need to connect to that archive database with the Change Auditor Client and it will initiate an upgrade of the database.
To accomplish this you will need to open the Change Auditor Client and on the "Profile" screen before you hit connect you need to select "Manage" on the bottom right. This will take you into the "Manage Connection Profiles" screen and from here you need to click on "Add" on the bottom left.
We should now be in the "Connection Wizard" screen and you need to select "Database Direct" (the very last one) and click next. On the next screen you need to select your SQL instance and the database you wish to upgrade. Click next and on this screen you need to name the Connection. Once this is done click on "Finish" on the bottom.
Then you need to select the connection and connect to it.
Once you connect it should prompt you and say "Wrong version database. Click yes to upgrade".
This will run all the required scripts to upgrade it to the version required.
Once it is completed you can then open and view the data from the CA client.
