I have set once to a website a lenght limit to a field. And now the client wants to put more charachters to that field.

I cannot change the max size value from Drupal. Because I get:

There is data for this field in the database. The field settings can no longer be changed.

However there must be a solution, shall I change it in database ? (is a field form Field-collections module)
