I have a M0 Sandbox shared cluster hosted with GCP in Mumbai region.
I want to transfer it to us-west.
When I tried to do it via the dashboard, I’m not even getting an option to review my changes
Any help would be appreciated here! Thanks
Hey @Balaji_Jayakumar,
Welcome to the MongoDB Community Forums! 
As per the Move a Cluster to a Different Region documentation, Atlas supports changing a cluster’s region and cloud provider:
- When you increase the cluster tier of an
M0,M2, orM5cluster. - Anytime on an
M10+multi-region cluster.
However, if you don’t want to upgrade to M2/M5 and don’t want to input new payment details, one workaround can be to mongodump your current M0, delete the M0 after the mongodump is complete (delete only once you have verified it has all the data), create a new M0, and then mongorestore to it.
Another safer option can be to create a new project, create a new M0, mongodump from the original M0 project, and then mongorestore to your new M0 project.

Hope this helps. Feel free to reach out for anything else as well.
