Acronis B&R 10 update question

Hello All

Im planning to update my old B&R 10 with the newest build which i have jut downloaded minutes ago.
My question is will i have to re-create all my backup plan tasks or will they remain unaltered after update? I would appreciate every comment as i wouldnt want to spend week recreating them.
Also on a side note did anyone experienced strange issue with B&R filling up backup drive with 100000000 of nonsense files (8 to 500kb each) instead of one big backup archive ?

Thanks again guys :-)
