We are recently migrated from exchange 03 to exchange 2010 with DAG configuration. We are also use baracuda as NLB. We have been running into a few problems such as outlook connection activity to exchange servers, email delay and public folder replication issue between exchange 03 and exchange 2010. I was able to menually replicated all the public folders to exchange 2010, but i am not able to completed replication the public folder instances. I'm waiting for all the public folders to diappear from public folder instances on exchange03 before i decommision exchange03. I recent shutdown all the exchange services on exchange 03, hoping to fix email delay.
Any suggestion will be deeply appreciated.
