Go-Live review is a complimentary technical review conducted by FlashGrid support before a customer cluster goes live. Please note that Go-Live review is mandatory for Production tier clusters. For non-production tier clusters the review is optional.
The review process must be initiated by the customer.
Why go through the Go-Live Review
- FlashGrid Support will verify that the cluster is in a healthy state and ready for production use.
- Only those production tier clusters that completed the Go-Live review are eligible for Emergency and Urgent severities of support tickets.
