Migrations and Hardware Upgrades to a vSphere Environment

Products

• Operations Manager

Issue/Introduction

Symptoms:

At some point throughout the course of operating a platform managed by Ops Manager, the need will arise to upgrade the underlying vSphere hardware or clusters. Upgrades like this come in many forms, but here are a few common examples:

• Adding a new vSphere cluster and availability zone in Ops Manager.
• Migrating from one cluster of ESXi servers to a completely different cluster of ESXi servers.
• Migrating from one vCenter server to a new vCenter server.
• Moving from one set of availability zones in Ops Manager to a new set of availability zones.
• Migrating virtual or physical networks, IP or other network changes.
• Renaming vSphere Datacenter, Cluster or Resource Pools
• Grouping Clusters in vSphere into folders
• Moving VMs from a resource pool to a top-level cluster or from a top-level cluster to a resource pool

It is important to understand that planning and executing migrations of this nature requires careful planning to avoid downtime or data loss.

Environment

Resolution

Migrations of this scope and nature need to be carefully planned and executed to avoid causing problems or outages. Migrations may also need to be performed during off hours or during the scheduled maintenance window as it may not be possible to perform such migrations without downtime. Every migration, environment, and situation are different from one another, though.

Customers who need to perform migrations or changes to the underlying IaaS should contact their Tanzu account representative, Tanzu platform architect, and Tanzu Support before the migration so that VMware Tanzu team can engage and assist with planning the migration.

Impact

Planning and executing a migration requires consideration of several factors depending on the nature of the change and the underlying IaaS. VMware Tanzu strongly recommends that you engage your Tanzu Platform Architect for the system review in all such cases to ensure a successful migration and to avoid extended downtime or data loss.
