Objective/Summary This article contains the main things to consider before upgrading the iTest environment. Environment/Versions Spirent iTest Procedure Spirent recommends to upgrade either from version to version or 1 -2 versions behind. Each new version is upgrade tested with the last 2 of its predecessors. Usually, before performing the upgrade, user must ensure the following: ⦁ license file will work with the desired iTEST version ⦁ only supported and compatible software versions will be used – VMs hosting iTEST and license server ⦁ system has a backup – in case something goes wrong with the upgrade iTest projects can be saved to a SVN/GIT repository or you can backup your workspace (simply copy it to a safe location or archive it) From iTest’s perspective there is no actual “upgrade” other than simply installing the software on your system and opening your workspace in the new version of iTest. iTest documentation as well as APT license server docs for each release can be found by logging in at https://support.spirent.com/SpirentCSC/SC_KnowledgeView?cid=null&id=DOC10692
