In Ex2007/Win2008 our old server (Porter, decommissioned) was a member of "Cert Publishers" and "Exchange Domain Servers".

In Ex2013/Win2012 our new server (Pebbles) is not a member of these two groups.

Does Pebbles need to be a member of the two groups ("Cert Publishers" and "Exchange Domain Servers") that Porter was?

Hi

Once you install exchange 2013 it will be put part of the groups it needs to be part of.

Was your previous server a 2010 or 2007 server?

Yes, Ex2007/Win2008 was our old server. 

I was pretty sure that Ex2013 would automatically add the groups it needs when it installs.  Just wanted to confirm it.

Also, can I remove the "Cert Publishers" and "Exchange Domain Servers" groups from AD; beings that the old server (Ex2007) is the only member in it as of now?
