Moving your tasks in Instagantt is very simple. There are two ways you can move your tasks:
Sometimes we need to reset the dates of task but we're still not sure of the new dates, so we may need to remove the dates of the task. To remove the dates, click on the name of the task and go to the Date field on the task details pane. Click on the three dots and select Remove dates. That's it! The dates of your task will be reset so you can enter new dates.
