Dell EMC Converged Systems Upgrade Guide from VMware vSphere 6.0 to VMware vSphere 6.5 This document describes the best practices and upgrade sequence for upgrading Converged Systems to the current release. This upgrade procedure is for Converged Systems that include the VMware vSphere Distributed Switch. The target audience for this document includes build teams, deployment and installation personnel, sales engineers, field consultants, advanced services specialists, and customers. Use these instructions to upgrade the following Converged System: VxBlock and Vblock Systems 240 VxBlock and Vblock Systems 340 VxBlock and Vblock Systems 350 VxBlock and Vblock Systems 540 VxBlock and Vblock Systems 740 Vblock System 720 This document also provides prerequisites and strategies to minimize system downtime. Note: In this document, all upgrades are on AMP-2V/AMP-2P/AMP-2HA/AMP-2RP/AMP-2S. Important: Starting with VMware vSphere 6.5, the Cisco Nexus 1000V is not supported. Dell EMC recommends migrating from the Cisco Nexus 1000V switch to the VMware Virtual Distributed Switch (VDS) before upgrading to vSphere 6.5. Important: If you are upgrading a Vblock System 720 from VMware vSphere 6.0 to 6.5, you must replace the HBA QLE2462 card with a QLE2562 card. If the Vblock System 720 conversion to the Vblock 740 is part of an upgrade then no HBA replacement is required. The Vblock 740 uses eMGMT that does not uses HBA cards and the AMP server is not connected to the VMAX through FC. This applicable to the Vblock 740 with VMAX3/VMAX All Flash. The Glossary provides terms, definitions, and acronyms.
