we are using jira in datacenter.
we have an attribute that is currently a string limited to 255 char.
we would like to be able to have more than 255 char.
it seems that we need to modify the type of the attribute. and for this, it seems we have to create a new attribute and remove the old one.
if we do like this we will loose all value for this attribute in the corresponding project and it is painfull to backup them.
what is the clever way to follow ? is it possible to modify the type of the attribute without creating a new one ?
