RE: What is “Pre-Upgrade” Step and why it’s taking more time for upgrade.
If you are upgrading Diyotta Controller from pre 3113 to any build after 3113, then installer will run “pre-upgrde” steps. These steps are the part of Installation script in which it will change the Diyotta Controller’s folder structure from “diserver/” to “diyotta/controller/”. During this process, it will copy all the files from diserver/ folder to “Diyotta/controller”. This process takes time depending upon the number of files present in old diserver. Once the folder structure is migrated, installer will execute the upgrade step.
