I’m trying to find best solution for migration all MongoDB cluster from 3.4 to 4.4. the old system is running on MongoDB 3.4 on RedHat 7.7, and I want to move all data with user information to MongoDB 4.4 on Redhat 7.9 on another server. I undertand that I can’t use mongodump/mongorestore utility since it didn’t include user information. I also understand that I can’t use mongoexport since it’s used for collection backup, not whole Database backup. So, I need your help to find the best solution for migrating all DB (not upgrading) to newer MongoDB on another server.
Thank you all in advance.
