Trying to upgrade from vix 5.2.43 to 5.3.01 (Edision Nino Pro) works fine but the backup restore feature does not bring all the features that were on the previous image i.e. key files, plugins, backdrop.mvi bootlogo.mvi plus the other stuff that makes 27.5w work etc. I had to restore a full image backup to get back to where I started. On my other box, Zgemma H7s, upgrades seamlessly. What settings should be selected when set up manually in the backup manager (yellow button)?
