Exchange 2003 to 2010 public folder migration

Hi!

My public folders will not for some reason migrate from Exchange 2003 to Exchange 2010.
All e-mail is migrated without problems and located on Exchange 2010 server...

I have followed the migration guide, but nothing happens. Nothing to see on eventviewer on Exchange 2003 or 2010 server. Where should I look else ?

If I use ExFolders program (ExFolders for Exchange 2010) I can't see any Replicas under "Replica".
Also in "Exchange System Manager" on Exchange 2003 server under "Tools / Monitoring and Status / Status" Exchange 2010 server is listed as "Unreachable".

Any help wil be appreciated !

Thx in advance,

:-) Jens
