Saving for College - Timeframe to move money from a UGMA to a 529

Thanks everyone. Planning for college in 2020. This will be for him in college. Will end up doing this next year. Anyone have any other good ideas for saving for college? My husband and I are both thinking of opening up Roth IRAs as well. That will help us pay for the later half of the education years for him. I’m trying to find ways that will help also qualify for financial aid in the future.
