Where are you running the Replica set? Self-hosted, or in MongoDB Atlas, or someplace else?

Also, please provide information on the versions of MongoDB you’re currently running… and the target version you wish to upgrade to.

running in mongoDB Atlas currently we using free version(8.0.5). Now we want to upgrade to M10 configuration.

Scaling up to an m10 from an m0 is relatively straight forward… here are the docs: https://www.mongodb.com/docs/atlas/scale-cluster/ and https://www.mongodb.com/docs/atlas/scale-cluster/#std-label-scale-cluster-instance specifically…

You’ll essentially visit your MongoDB Atlas UI console and click Modify cluster. Select a new tier (m10). MongoDB atlas will deploy a new m10 instance in the background and migrate your data from your m0 instance to the newly deployed m10 instance.

Hope this helps… let us know how you make out.
