But! if you run an old device no longer receiving new firmware or are at the tip of stock-rom firmware updates, there’s the option to transition with userdata intact using a workaround. It’s a testers approach… that worked for me™

It has worked for me on several official Sony Xperia devices, moving from e-0.18-q dev builds to e-0.18-r test builds. In brief the steps - all in TWRP - are

0. Backup your existing data partition. (This isn’t actually necessary, but it will make you feel better )
1. Flash the new R ROM (I used the test build I have just made e-0.18-r-20210910-UNOFFICIAL-suzuran)
2. Advanced > File Manager navigate to /data/user_de/0/org.lineageos.lineagesettings/databases/ and delete both files there (lineagesettings.db and lineagesettings.db-journal)
3. Wipe cache / dalvik
4. Reboot system
