delete checkpoint

Hi,

need quick confirmation before deleting checkpoints...

Server 2012R2 Host - server 2012R2 VM with 2 checkpoints after all configurations done.

Want to merge checkpoints.

Even on test machines I never tried to delete Checkpoint Subtree.

Question 1.

Would it be more  secure to delete checkpoints one by one with a shutdown after each deletion or I can click on top one and delete subtree?

Question 2.

Also, just for the information...

Let say I have 5 checkpoints and want to merge all of them one by one, would  the order of deletion matter?

Thanks.
