This document serves as a guide for users undertaking the migration of BDRSuite storage volumes between drives with different drive letters.

Step 1: Stop BDRSuite Service

From the SGTray application located in the Windows taskbar notification section, stop the BDRSuite service before initiating storage migration.

Step 2: Database Dump (Optional)

To ensure safety, take a dump of the main database (SGDatabase) using the following steps:

1. Open the command prompt with administrator privileges.
   

1. Navigate to the PostgreSQL bin location
   

Example: cd "C:\Program Files\Vembu\PostgreSQL\<postgres Version>\bin"

3. Run the command:
   

pg_dump.exe -U postgres -p32010 -d SGDatabase > C:\SGDatabase_Dump.sql

Note: If prompted for a password, type "admin" and press Enter.

Step 3: Copy sgstorage Folder

Copy the `sgstorage` folder from the old storage location to the new storage location. Ensure successful data transfer before proceeding.

Step 4: Run Storage Migration Util

1. Open the command prompt with administrator privileges.
2. Navigate to the VembuBDR installation location (e.g., `cd "C:\Program Files\Vembu\VembuBDR"`).
3. Run the utility with the following command:
   

  bin\VembuBDR.exe ChangeRepository <Old_Storage_Drive> <New_Storage_Drive> <PoolName>

  Example:  bin\VembuBDR.exe ChangeRepository E:/ D:/ FirstStoragePool

1. If multiple storage pools are configured, repeat the command for each pool.
   

Example:

  bin\VembuBDR.exe ChangeRepository E:/ D:/ FirstStoragePool

  bin\VembuBDR.exe ChangeRepository X:/ D:/ SecondStoragePool

1. If you have configured network drive as your backup repository, you have to run the above command by specifying the Storage Pool names.
   

Example: bin\VembuBDR.exe ChangeRepository //192.168.x.x/d$  //192.168.x.x/c$

Step 5:  Retrieve the list of configured storage pools:

1. Open CMD and navigate to the PostgreSQL installation location.
2. Run the command:
   

psql.exe -U postgres -p32010   

Note: If prompted for a password, type "admin" and press Enter.

1. Enter the following commands:
   

\c SGDatabase

select repository_name from sg_chunk_repository_details where Global_repo_id in (0, -1);

Note: The above query will provide the PoolName.

Step 6: Completion and Server Start

Once the storage migration util process is completed, start the BDRSuite Backup server.
