Question : Move Public folders from exchange 2003 to exchange 2007

I have recently migrated my exchange 2003 server to exchange 2007 sp1, and i'm trying to move my public folders from 2003>2007 so i can decommission the 2003 box. I have followed this article, (http://msmvps.com/blogs/andersonpatricio/archive/2007/10/30/moving-all-replicas-from-an-exchange-server-2003-to-an-exchange-server-2007.aspx) however, my folders are not "dissappearing" as they should.

What about the mailflow between bothe servers ....Public folder replicates in form of mails
Send a mail from legacy to new server and vise-versa and see if you receive them.

Make sure you can telnet each other's port 25

Try to ping FQDN of exchane 2007 from ex 2003 and vise-versa

make sure there is routing group connector
get-routinggroupconnector

if it is already there just delete it and re-create bidirectional routing group connector it
New-RoutingGroupConnector
