Upgrading to v2 scheduler

i want to upgrade to v2 scheduler so i can randomize all my subdecks and i have no cards in the learning phase (i’ve stopped adding new cards so i can move my learning cards to the review phase and i’ve checked it with is:learn on the browser and it is empty) is there anything i should know before upgrading ?
i’m afraid it would affect sotmething else since it is called beta v2

i don’t think there is anything to be afraid about. i have been using it for a while now, and had no issues.
here’s all you need to know about it.
