[Users] Is it safe to remove the `default` COS?

[Info Zeta Alliance]

Hello All, 

After doing a side-by-side migration using Zextras, I ended up with these 2 COS'es: 

default_restored_zimbra1.example.com 
and 
default 

Where as `default` is a newly created COS by the installer, and the ` default_restored_zimbra1.example.com` 
is the one where are the migrated users ended up in. 

I know I can set the default cos for a domain using; 
zmprov md example.com zimbraDomainDefaultCOSId <uuid of default_restored_zimbra1.example.com here > 

I have verified that there are no more users in `default` but I want to prevent admins to accidentally add 
users into it. 

Can I hit the delete button on the `default` and then rename default_restored_zimbra1.example.com to default? 

Or would that break something? 

Kind regards,
