Update the instance type of AWS DocumentDB
We've been using documentDB for few months, the current instance type seems not enough since we started seeing exception in our application (yes alarm is not set yet)
MongoDB.Driver.MongoWriteException: A write operation resulted in an error. Operation timed out due to low available memory.
Can I change instance type of aws DocumentDB without losing Database or Data?

With Amazon DocumentDB, the storage layer is decoupled from compute. You can scale at any time (either by adding a bigger instance, fail over to have the new instance the new Primary and then delete the old instance, or just by changing the type of the current instance) without losing any data. Furthermore, data is backed up (1 day retention by default) and streamed continuously to Amazon S3, for additional peace of mind.
