Can we still schedule HHG with orders, or does it need to wait until after the SECDEF memo order?

No, the stop movement impacts all of the aspects of a PCS

If your report date is within the period, most likely you will get a new report date. The Army is trying to avoid the situation that all SMs PCS on the same day and ruin the PCS cycle. HRC is working on order amendments already. My NCOIC’s report date was in April but now it is in August.

I read that non first time PCS have been canceled.
