How to Update from LineageOS 19 Android 12 to LineageOS 20 Android 13

Does the old data still remain on the cell phone? So banking apps and images?

Thank you for making the effort to make this video :)

what was the point of downloading the recovery?

I have lineagesos 19.1 and I want to get it to 20 but my phone (a51 4g) does not have the rom for the 20. Will it come out later or am I stuck on lineage os 19? Please answer I am begging

How can i remove MindTheGApps and then install Nick GApps Core? Thanks, great video!
