Can I keep my earned bao after the migration without loss?

I just read the post about the migration do Dai but I still didnt fully understand one thing:

Since there was some ambiguity to this, I will clarify that March 1st is the LAST day to harvest on the mainnet contract without penalty.

Does this mean that if I dont harvest the earned bao that I have in the eth/bao farm Im gonna lose some amount of these tokens?

You need to harvest by March 1, otherwise you will lose 75% of your harvestable Bao.
