To clarify, I'll give what is mentioned in the Integration Manager User's Guide:
Converting a database
Use the Database Conversion window to convert a database from a previous
version of Integration Manager to an (newer) Integration Manager.
To convert a database:
1. Open the Database Conversion window.
(Tools > Convert Database)
2. Click Select Database. Browse to the location of the database to convert and
select the database.
3. Click Open.
4. Click Convert Database. The database is converted and a check mark is added
to each step when the conversion for that step is completed successfully. The
new file (Converted_<Name of database>) and a log file (Converted__<Name
of database>.log) are saved to the same folder location as the original database.
If any of the steps in the list were not completed or converted successfully, a warning
icon is displayed by that step. Click the warning icon to find out why the step was not
converted successfully. You can view the log file (Converted__<Name of database>.log)
to find out more information about a conversion that was not completed successfully.
5. Click OK when the conversion complete message is displayed.
6. When you are finished, click Close to close the Database Conversion window.
You can click on the converted database file to open Integration Manager.
You can complete the following optional tasks.
• Rename the database file.
• Change the file extension. You can change the file extension to .mdb.
If the file extension is .imd, you can double click the file to open your
Integration Manager database. If you change the extension to .mdb, you’ll
need to open the database file from Integration Manager.
• Change the path of the converted file (Tools > Options).
