Field change from Drop down single select to Multi select picker

[Prabhu Chilukuri]

Hi Team,

Is there a way to change the field type Single select drop down to Multiple picker field?

Thanks,

Not on Cloud (you can do this safely on server with a database hack)

All you can do is add a new multi-select list, and migrate the existing data into it, before removing the old field.
