How about using a new custom field?

Hai,

Thanks for reply.

Our requirement is to change the existing custom field from string to text area as we have linked this to few of the existing projects. Please suggest is this possible

Can be done but if you want to preserve data, you first need to export it and after the change import it again.

data stored in custom field got deleted.

There is no data deleted after changing a type.
It's is still stored in table mantis_mantis_custom_field_string_table" column "value".
After changing the type to "Textarea", the data is read from column "text"
So all you have to do is to copy the data from column "value" to column "text"

Perfect, then it becomes an easy change
