We currently use Alpha 4 version 2.1.11 and we are thinking of upgrading the version for quite sometime now (preferably to Alpha 5 but will settle for upgrade). What is the best way to upgrade without much problems with all the applications that are currently doing well with the current version we have? Can you go to Alpha 4 ver 7 from the current version we have or we have to convert our application to a lower version than 7? Thanks for your help.
