Hello. Will I am able to switch (I mean upgrade or downgrade) Amazon RDS instance on need basis or do I have to create a new afresh and go through migration?

A:
Yes, Amazon RDS instances are upgradeable via the modify-db-instance command. There is no need for data migration.
From the Amazon RDS Documentation:
"If you're unsure how much CPU you need, we recommend starting with the db.m1.small DB Instance class and monitoring CPU utilization with Amazon's CloudWatch service. If your DB Instance is CPU bound, you can easily upgrade to a larger DB Instance class using the rds-modify-db-instance command.
Amazon RDS will perform the upgrade during the next maintenance window. If you want the upgrade to be performed now, rather than waiting for the maintenance window, specify the --apply-immediately option. Warning: changing the DB Instance class requires a brief outage for your DB Instance."

Wow ... this is brilliant. I wasn't expecting a +ve reply :) ... I am just hoping there is no downtime during upgrade.
