How to migrate a PostgreSQL 10 database from Windows C drive to another drive
To migrate a PostgreSQL 10 database from the Windows C drive to another drive, you can follow these general steps:
Stop PostgreSQL: Before starting the migration process, make sure to stop the PostgreSQL service to prevent any data inconsistencies or conflicts. You can stop the service using the Services management console or by running the command
net stop postgresql-x64-10
in an elevated command prompt.Copy the Database Directory: Locate the PostgreSQL data directory on the Windows C drive. By default, it is located in the
C:\Program Files\PostgreSQL\10\data
directory. Copy the entire contents of this directory to the destination drive or folder where you want to migrate the database.Update PostgreSQL Configuration: Once the data directory is copied, you need to update the PostgreSQL configuration file to reflect the new data directory location. Open the
postgresql.conf
file located in the data directory of the new drive using a text editor. Search for thedata_directory
parameter and update it with the new path to the data directory. Save the changes.Update Windows Registry (Optional): If you have modified the Windows registry to specify the data directory location, update the registry key as well. The key is located at
HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL\Installations\postgresql-x64-10
in the Windows registry. Update theData Directory
value with the new path to the data directory.Start PostgreSQL: After updating the configuration and registry (if necessary), start the PostgreSQL service again. You can start the service using the Services management console or by running the command
net start postgresql-x64-10
in an elevated command prompt.Verify Database Accessibility: Once the service is running, check if you can access and use the migrated database. Connect to the PostgreSQL server using your preferred client application and perform some basic operations to ensure that the migration was successful.
By following these steps, you should be able to migrate a PostgreSQL 10 database from the Windows C drive to another drive or folder location. It is always recommended to perform a backup of the database before making any changes to ensure data safety.
