Redmine

Hi there,

I need a help regarding custom property updation from backend without disrupting its existing values in trackers.
I am currently using Redmine 2.4.2. Now there is a custom field mentioned in attached image (Image_One.png)
This custom property is already used in many projects. When created this custom property, we accidentally assigned its Format as List.

Now we have decided to install Redmine to latest version i.e 2.5.2 in new server. I restored db in new server. Everything is working fine. I want to change this custom field format to user type from List type along with filtering based on role basis as shown in attached image (Image_Two.png)

As this facility is only available for Newly created custom fields. I need help for changing existing custom property format to above mentioned custom property's user type without harming existing data

Or

Silent way to update existing data with user format type so that when user update this custom property in new trackers, they should get filtered user based on user type. I know that this can be carried out only in database level. Please suggest a way to do so.........
