Dell EMC upgrade guide for the Converged System you need to upgrade Note: In this document, all upgrades are on AMP-2P, AMP-2HA, AMP-2RP, and AMP-2S. Note: AMP-2V applies to Vblock System 240 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 upgrade a Vblock System 720 from VMware vSphere 5.5 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 with AMP-2S uses eMGMT, which does not require an HBA card to connect the AMP server to the VMAX/VMAX3/VMAX All Flash through FC. The Glossary provides terms, definitions, and acronyms.
