12-25 will work fine as your chain is already long enough (being able to handle a 32) and your derailleur already has enough capacity ( being able to handle an 11).

Only thing to watch out for is not to let cassettes or chains wear much or one old cassette can wreck a chain which then wrecks the other cassette. Keep everything in good nick and there's no issues.
