How do I migrate a project from GCP Kubernetes to DigitalOcean Kubernetes ?

I’m not aware of a good blog post, but I have gone through the process and I can provide a bit of guidance.

For me, the high-level overview of the process was as follows:

1. I needed a container registry as I had been hosting my registry in GCP. I signed up for the DO Beta Container Registry as my solution.

2. I uploaded my containers to the DO Container Registry

3. I provisioned a Kubernetes cluster on DO

4. I built all of the required containers and components in the new Kubernetes cluster by altering my scripts to point at DO Container Registry and the DO Kubernetes cluster.

5. I disabled all outgoing email servers on my new cluster while I tested.

6. I loaded a backup of my data into my DO environment

7. I tested the environment using hosts records locally to point at the new site

8. I put my production site into maintenance mode and generated a final data dump.

9. Loaded the data dump into DO and re-tested the system.

10. I re-enabled outbound emails on the new cluster.

11. I adjusted my DNS record to point at the DO Kubernetes cluster.

12. I waited 48 hours to ensure things were smooth and then I deleted the GCP cluster and resources.
