We have multiple Pritunl instances, each one running their own local MongoDB host.
We would like to unify these instances into a single, external MongoDB to form a cluster.
What would be the best migration path to accomplish this? I know I could copy the contents from one of the MongoDB’s, but then I’m not sure how I would handle the other ones. I want to preserve existing user profiles as much as possible to avoid additional work. Are there any trouble related to standalone servers becoming nodes in a cluster?
I was thinking also of only exporting certain MongoDB collections and joining them, but I’m not sure if this would work.
Any help is greatly appreciated!
