Topic: How to upgrade GCP Postgresql from old version to the new version by using Database Migration DMS in GCP.
Here’s a step-by-step
guide to upgrading GCP PostgreSQL from an old version to a new version by using
Database Migration Service (DMS) in GCP:
1. Create a service
account in the Google
Cloud Console with the necessary permissions to access your GCP project,
PostgreSQL instance, and DMS. You can follow the instructions provided in the
official documentation.
2. Install the Google
Cloud SDK on your local
machine. You can download it from the official website.
3. Authenticate your Google Cloud SDK by running the
following command in your terminal:
4. gcloud auth login
5. Set your project ID by running the following command in your
terminal:
6. gcloud config set
project <project-id>
7. Create a migration job by running the following command in your
terminal:
8. gcloud dms
create-migration <migration-name>
--source_database_host=<source-host> --source_database_port=<source-port>
--destination_database_host=<destination-host>
--destination_database_port=<destination-port>
--reverse_ssh_tunnel=<True/False>
Replace <migration-name> with a name for your migration
job, <source-host> and <source-port> with the hostname and port number of
your source PostgreSQL instance, and <destination-host> and <destination-port> with the hostname and port number of
your destination PostgreSQL instance. Set --reverse_ssh_tunnel to True if you need to use a reverse SSH tunnel for connectivity.
9. Start the migration
job by running the
following command in your terminal:
gcloud dms
start-migration <migration-name>
10. Monitor the migration
status by running the
following command in your terminal:
gcloud dms
describe-migration <migration-name>
11. Verify the migration by checking that all data has been
migrated successfully to the new PostgreSQL instance.
That’s it! You should now have upgraded your
GCP PostgreSQL instance from an old version to a new version using DMS.
I hope this helps! Let me know if you have any
questions.
