Engagement casts - change

Hey there,

Long story short - due to a new website we've had to turn off our nurtures for a few week. I'm slowly fixing content and activating some pieces. Issue is that for some of them their next send would be Thanksgiving. I want to bump them up to a different day or this Thursday just to make sure they don't go a month without an email (that would just be horrible :) ) and don't want it going out Tgiving.

Question - If I change the "start date" on the stream cadences to make it this Thursday will that mess up any of my past send history etc?

Thanks!
