 Description   

It would be nice if there was a fleshed-out cookbook of verified commands to run when migrating a cluster to new shards for whatever reason. Currently it seems like you need to cobble together this stuff from a lot of disparate doc pages, unless I'm missing something.

Related to DOCS-95.

I think the goal for this ticket is to write a tutorial or tutorials for "Migrate Shard Cluster to New Hardware" with the following steps:

0. Disable the balancer

1. Migrate each replica starting with the secondaries.

2. Migrate the config servers one at a time

3. Migrate/reconfigre the mongos.

4. Enable the balancer.

Ideally tutorial would provide a high level overview linking to a collection of other tutorials that outline the actual process and a quick overview of the entire process.

Greg, can you elaborate on this? Do you mean like loading data to a new shard cluster?

Docs you used for this process?
