Wiping data might not be needed is you try the migration scripts from unofficial to official that I provided on page 11. I have been using them succesfully for lineageos 17 and older versions.Oneplus 5 build is meant to be today and the 5T build tomorrow. I'd wait until they're released and then flash those ones as flashing unofficial and then official would mean wiping data again. Or at least that's what a previous comment said.
Yes, this first than all the other zips you want to flash.Do I just flash this before flashing the official build?
