Exporting and importing workflows, and restoring from backup snapshots
Good morning. How can we export and import our workflow backup snapshots
from one established NiFi server instance to a new instance of NiFi stood
up on a new server?
Also, how does one restore a previous version of a workflow backup snapshot
created from the administrative tool?
Thank you. -Jim

Thank you very much for your patience with my questions Andy. I will do
that for pages I choose to watch.

Jim,
If you have or create an account with Confluence, you can receive notifications. There is a “Watch” button at the top right of each page which will subscribe you to email notifications when the page changes.

Thank you very much Bryan. I will look more closely for archives, and into
transfers for the time being using flow.xml.gz. I also hope to see if
there's a way to be alerted to changes on the Confluence page you cited in
your reply. -Jim

Re: Exporting and importing workflows, and restoring from backup snapshots

Hello,
Moving flows between NiFi instances is definitely something the
community is working to improve [1].
Currently there are two main options: templates, or moving the whole
flow.xml.gz.
You can create templates of process groups and then import them into
another instance, some people have gone as far as automating this with
scripts using the REST API.
If you want to whole sale move the flow you can just copy
conf/flow.xml.gz from one instance to another, keeping in mind that if
you have processors with sensitive properties, you will need the same
encryption key in both environments.
I believe the backups work similarly to copying the flow.xml.gz in
that there should be an archive directory with copies of the
flow.xml.gz from different snapshots, and you can stop NiFi and copy
one of them into conf as the flow.xml.gz. Maybe someone can correct me
if I am wrong here.
Thanks.
Bryan
