The essential difference between standard and multitenant (MT) environments is the adding the database column pztenantid for many tables for MT. MT and High Availability (HA) are two separate concepts. I do not believe we currently support upgrade from standard to MT. To support HA, the critical requirement is the support of split schema (data and rules). I believe the support of MT+split schema is only available since 7.1.5 (not 100% sure). See https://collaborate.pega.com/question/deployment-guides for details regarding both MT and HA.
