Change/Migrate PostgreSQL to MS-SQL Server

In a simple three stage process, migrate the PostgreSQL data and run the RecoveryManager Plus Server with MS SQL Server.

Backing up PostgreSQL Data

  1. Stop the RecoveryManager Plus Server/Service.
  2. Invoke the  <RecoveryManager Plus Home>\bin\backupDB.bat in command prompt, to backup the data available in PostgreSQL database. By default backup file will be stored under <RecoveryManager Plus Home>\Backup\OfflineBackup_YYYYMMDDHHmmss directory .

Configuring MS SQL Server

Common Settings to be performed in MS SQL Server

  1. Open SQL Server Configuration Manager.
  2. Goto ‘SQL Server Services’ and ensure the service 'SQL Server Browser' is running.
  3. Goto SQL Server Network Configuration → Protocols for SQLEXPRESS (the given instance while configuring the MS SQL) →Enable TCP/IP. Then restart the SQL Server (SQLEXPRESS - the given instance) Service.
  4. Set the following configuration for the SQL Server Configuration Manager:
    • SQL Server Network Configuration → Protocols for <instances> → Enable everything.
    • SQL Native Client Configuration → Client Protocols → Enable all.

Providing credentials to other users in the domain

If not, right click the Logins, New Login and provide a corresponding user name. The New user must have the sysadmin server level role and database level role of db_owner.
Follow the steps to provide the sysadmin role permission:
Right click the user, click 'Properties'
Go to 'Server Roles' → Check sysadmin and click 'OK'

Note: Details about user roles: Refer the documents in the following links:

For Server Level Roles: http://msdn.microsoft.com/en-us/library/ms188659.aspx

For Database Level Roles: http://msdn.microsoft.com/en-us/library/ms189121.aspx

For additional resources: http://www.mssqlcity.com/Articles/Adm/SQL70Roles.htm

Server Role of the user should be 'sysadmin' and Database Role of the user should be 'db_owner'.

The members of sysadmin server role can perform any activity in SQL Server and have completes control over all database functions.

The members of db_owner database role can perform any activity in the database.
