Hi Stennie,
Thanks a lot for sharing your suggestions. We will take this into our considerations and we will slowly upgrade into the latest versions in new UAT environment first and perform the full functional testing between each upgrade.
Secondly, We are planning to move the whole sharded cluster to completely newer hardware in different location. In this case, How we can migrate the whole setup from one environment to another? How long will it take roughly for 5 databases each 1 TB in size?
And, Is there any option to migrate without any downtime or with minimal down time?
Thanks,
Arun.
