The update says the week of Nov 1 at the earliest.

Season of Mastery Transfers Update - Nov. 1

Update: Season of Mastery players can now transfer their characters for free to a Classic Era realm or to a Wrath Classic realm of the same ruleset (Normal or PvP). Please be advised that this transfer is one way only and final. Your decision cannot be changed or reversed. Greetings, As Kaivax mentioned here, we started opening the Free Character Migration service from Season of Mastery to both Classic Era and Wrath Classic realms earlier this week, and then had to disable it to resolve a bug…

This is for SoM characters.
No announcement for anyone else.
