Move security groups to new OU

My Domain Admins are going through an AD redesign and need to move the CRM security groups to a new OU.

Are there any gatchas to keep in mind with the OU move?

Do I need to run a repair of CRM to map to the new OU?

I've tested with a DEV environment and haven't noticed any impact of the OU move for those security groups.

Thanks!
