Get Error Duplicate name Task TASK00002 already exists


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.

Any ideas?

please provide screen shot

ok. I’m trying something else at the moment by exporting and then re-importing without ID or naming series to let the system recreate them cleanly. If this doesnt work I’ll add a screen shot

This worked after deleting the existing records.
