Migrating the Virtual I/O Server by using the viosupgrade command or by using the manual method
Learn how to upgrade Virtual I/O Server (VIOS) from VIOS version 2.2.x.x. to VIOS version 3.1.0.00. If the VIOS belongs to a Shared Storage Pool (SSP) cluster, the minimum supported level for upgrade to version 3.1 is 2.2.4.x. If the current VIOS version that belongs to an SSP is earlier than 18.104.22.168 (for example, VIOS version 2.2.3.x), you must upgrade to currently supported VIOS versions (such as, VIOS version 2.2.5.x or 2.2.6.x) before attempting to upgrade to VIOS version 22.214.171.124, or later.
