Postgres Migration Tool: Step-by-Step Walkthroughs

To migrate PostgreSQL database to a new server (in cases of homogeneous migration, where the source and target databases are of the same DBMS), you only need to follow two simple, fully automated steps:

1. Create a full database backup.
2. Upload database backup file to another PostgreSQL server.

Here you can find a short instruction on how to migrate PostgreSQL database with Handy Backup tool. For more detailed information on each step, please read the appropriate sections of the User Manual.

Creating a PostgreSQL Backup

You can easily migrate your PostgreSQL database to a new server with the help of PostgreSQL backup tool. First, you need to create a backup task. Please make sure, that your data storage device, where backup file is created (for example, your FTP server or external USB drive), has enough available space (at least for the time being!).

1. From the menu bar at the top of the screen, go to File > New Task and choose a "Backup" task type. Select advanced mode for the advanced settings.

2. On step 2 select PostgreSQL from the Database folder.

3. Create a new PostgreSQL configuration for server migration if you still don′t have one.
4. Click "Create a connection" and enter your PostgreSQL connection parameters in the dialog box.

5. Now you have a configuration to back up PostgreSQL. Select your configuration and choose migrating databases.
6. Now go back to Step 3 and select a folder where you want to store your Postgres migration data.
7. Proceed with creating a task with default parameters, according to your backup strategy. Here you can use such advanced parameters as differential and versioned backup on Step 4, scheduling and triggering a task on Step 6, and starting external software on Step 7.

Caveat: To take a snapshot for PostgreSQL migration, you must have a sufficient user privileges to use a PostgreSQL SELECT statement freely for creating a backup database dump.

Using a Backup Dump to Migrate PostgreSQL to a New Server

Next, you will need to create a new PostgreSQL restoration task to migrate Postgres database to another server. Please follow the instruction below:

1. Create a new task and select restoration as a task type. Use advanced mode.
2. On Step 2, select a backup location where you have saved your Postgres snapshot.
3. Find a file backup.hbi, containing all data related to this particular backup. Click "Next".

4. Click on the "Change Location" button. Select a new server to migrate PostgreSQL database.
5. Click OK. Continue creating a task with default restoration parameters.

Note: Server Backup solution can perform both backup and restore operations needed for PostgreSQL migration on remote machines in the local network! In addition, single-machine editions like Small Business Backup software can also access remote databases.

Implementing a Postgres Database Migration Tool

Finally, you may migrate PostgreSQL to another server. In order to do so, start a backup task created in a previous instruction. After finishing this task, start a second part of the job – a restoration task. That is all! Your PostgreSQL migration will complete in fully automated mode!

An advice: Using the scheduling on the Step 6 of backup task (and the Step 4 or Step 5 of restore task), you can schedule your tasks to run automatically in an appropriate time (e.g. at evening after work hours). This can save you some time and efforts, although it may look a bit uncontrollable (or may not?).

How to Migrate PostgreSQL Database to a different database management system?

Migrating a PostgreSQL database to a new server with a different Database Management System (DBMS) requires a multi-step process. Since you′re migrating from PostgreSQL to a different DBMS, you′ll need to perform a conversion of the schema and data to the target DBMS′s format. You can migrate Postgres to SQL, Microsoft SQL or Oracle servers. Each of them has different specifications, however, here′s a general outline of the process

1. Set up the new server: Install and configure the new DBMS on the new server. Ensure it′s compatible with your application and meets the necessary requirements.
2. Understand the target DBMS: Familiarize yourself with the syntax, data types, and limitations of the target DBMS. This knowledge will be useful during the conversion process.
3. Export the PostgreSQL schema: Use a tool like pg_dump to export the PostgreSQL database schema. This command generates a SQL script containing the schema definitions, table structures, constraints, and indexes.
4. Convert the schema: Modify the exported PostgreSQL schema SQL script to match the syntax and structure of the target DBMS. This may involve changing data types, rewriting queries, and handling any incompatibilities between the two systems.
5. Create the schema on the new DBMS: Execute the converted schema SQL script on the new DBMS to create the necessary tables, views, indexes, and other database objects.
6. Export PostgreSQL data: Use pg_dump to export the data from the PostgreSQL database.
7. Convert the data: Modify the exported data SQL script to match the target DBMS′s syntax and any necessary data conversions.
8. Import data into the new DBMS: Execute the converted data SQL script on the new DBMS to import the data into the corresponding tables.

It′s important to note that the specific steps and tools may vary depending on the target DBMS you′re migrating to. Ensure you consult the documentation and resources provided by the DBMS vendor to understand the migration process in detail for your specific case.
