I exported my ERPNext Tasks from one install and imported them via a excel file into a fresh install.
But when I create a new Task in my new install i get the following error …
Duplicate name Task TASK00002
Task TASK00002 already exists
This is because the naming series may not have been updated with the very latest new task number. But when I try to use a naming series for Tasks and starting at say 50, it still didnt work.
