Absolutely.
When migrating data from one version to the next if there are fields that aren't in the old version that are in the new version, or are variable in the old version but not editable in the new version, then you simply provide a default value that makes sense and use it.
If the user wants to go in and edit one or two new fields to something other than the default after they've migrated from old version to new version then it's not a problem. Simply open the stadium on the new version and adjust whatever value was set as the default to whatever the user wants. This assumes the field is editable in the new version. If it's not editable then the user gets the default.
This is data migration 101 type of stuff. Very easy to do.
