Restoring backup from XperiaX didn’t work completely on my 10ii. Gallery, browser and messages worked. I dont know about calendar, because I dont use it.
Notes and People (contacts) did not transfer.
The workaround from Garak for the contacts is:
" I just extracted ./People/data/all.vcf (I think that was the file name) from backup and imported all.vcf from Peope app settings (Settings/Apps/People; there’s an option labelled “From contact file”). Almost forgot; I had to place all.vcf to either into ~/Documents or into ~/Downloads folder for the import to find it."
For the notes, I´m going to copy/paste them from a document-file…
As you can see, it´s not really flawless, but doable…
