Public Folders : remove replication to old server

Hi,
I'm moving everything off our old Exchange 2000 Server onto a new Exchange 2003 SP2 cluster. So far I've completed moving all the mailboxes, but I have a question about public folders.
I initially replicated ALL public/system folders between both servers. I now have the below folders replicated on both new and old servers:  We will be completely deinstall exchange 2000 from old Exchange server and remove it from the network over the next few weeks. Question is , can I safely remove all these system folders from replicating to the old server now??
