If you are using Diamond Mind Baseball version 11 and you have upgraded from an earlier version (DMB Version 8, 9 or 10), you will likely want to convert your existing season databases to the new format. When you need to convert an existing database that is installed in a previous version, the Copy database command is the best choice.

Note - It is possible to convert an existing database by using Windows file management tools to make a copy of the database folder and then use DMB's Add reference to existing database command to convert to the new format. The Copy database command simplifies the conversion process by combining those steps into one.

To copy an existing DMB database and convert it to version 11:

1. Begin by opening Diamond Mind Baseball version 11.

2. Click File on the DMB menu bar and select Copy database to open the Copy existing database window:


DMB assumes that you want to copy the active database so this location is entered for you in the Location of the existing database box. DMB also assumes that you will want to save the newly copied database to the main DMB folder so this location is entered for you in the Location for the new database box.

3. Since you want to convert a database from a previous version of DMB to version 11, you will need to choose a different existing database folder location than the one DMB has entered for you. Click the 2c026fa116d461944e1e292d2a50839168ea0df0 button to the right of the Location of the existing database box to open the Old database location window:


In the Old database location window, navigate to the folder location of the existing database in the previous version of DMB that you wish to convert and double-click the database folder name to select it. For example, if you want to convert a season that you have in progress in DMB Version 10, navigate to the dmb10 folder (usually, C:\dmb10) and then select the database folder of the season to copy. 

Note -The Old database location window requires you to double-click on each folder to open it as you navigate.

When you have selected the folder location of the database you want to convert, click the OK button to return to the Copy existing database window.

4. In the Name of the new database box, enter a name for the new database.  If you are copying a database from a previous version of DMB, you may use the same name for the new database. For example, if the existing season database was stored in a folder named "C:\dmb10\agt3_v10", you could use "agt3_v11" for the name of the new database and it will be stored in a new folder named "C:\dmb11\agt3_v11".


Note - The location for the new database will be filled in for you. By default, the location will be the DMB installation folder. This is generally where all your databases will be saved, so there's no need to change this.

5. Click the OK button to begin the conversion process. DMB will make a copy of the existing database folder in the new location and then check to see what version the database files are in. If DMB detects that this new database is not already in version 10 format, it asks you whether you wish to convert it to version 10. 

If you click No, DMB will not convert the database and it will not allow the new database to become the active database. If you click Yes, DMB converts the data from its old format to the new version 10 format.

DMB converts all of the information that was contained in the existing database, including:
  • all eras, leagues, parks, teams, players (with all of their real-life statistics and ratings), schedules, real-life transactions and lineups (if present), and notes
  • game results, statistics, injury logs, and transaction logs for games played with DMB
In other words, even if you are in the middle of playing a season, you can convert a database to the new format and pick up right where you left off.
Note - DMB 11 cannot convert data in formats older than version 8.

6. When the conversion is complete, you have the option to view a log of the conversion activity. In most cases, the log will simply report that the conversion was able to successfully convert everything in your database. If any problems were encountered, the log will contain warnings or error messages.


7. Click OK to continue. If no problems have been encountered, the newly copied and converted database will now be the active database.
