NSO Upgrade to 6.1.6

[Elvin J]

I want to upgrade existing NSO instance (5.8) to NSO 6.1.6.

What is the best practice to upgrade without losing data ?   I have ned packages and some conf files, how can I move them as well to NSO 6.1.6 more efficiently ? 

Any feedbacks are highly appreciated.

Have you already reviewed the "Administration guide" documentation on this.

Thank you for your response. I have the Docker images. However, what remains unclear to me is how to perform the upgrade with Docker images. Currently, I have a Docker image of NSO 5.8, which we created from scratch using the nso-docker tool. Now, NSO 6.1.6 already provides a Docker image. If it were a virtual machine (VM), the upgrade process would be straightforward with the provided link. In the case of Docker images, I'm unsure about the steps to follow.

How we do it with our nso-docker environment is as follows:

- First: We have shared storage for our containers (where the cdb is located).

- We create a backup (docker exec -t nso bash -lc 'ncs-backup')

- We stop (all) the containers

- We remove all the unused images

- We pull the new container (build with the newest neds, and also containing old neds which are build for the new version)

- We start the new container

- We check if the new container runs

Note: we started using nso-docker at version 6.0
