HI Guys,i have a below senario.i am running all roles in 1 server.Now i need to split it to 3 server and 1 for HT,CAS and other 2 servers for MBX.Can you tell me proper order for migrate all roles to 3 servers.Regards

hi,install new roles on your exchange server organization on the new servers. then move databases to new servers. leave CAS role on your existing server.after moving databases to new servers then you can uninstall your old mailbox server roles from your existing server. setup /mode:uninstall /role:MBfor detailed information : https://technet.microsoft.com/en-us/library/bb124115.aspxand also you can create CCR with your three servers. it will provide you high availability option.two server will be a mailbox and one of them will be a CAS/HT server. for FSW you can use your domain controller or another server.http://www.msexchange.org/tutorials/Installing-Configuring-Testing-Exchange-2007-Cluster-Continuous-Replication-Based-Mailbox-Server-Part3.htmlhttp://www.msexchange.org/articles_tutorials/exchange-server-2007/high-availability-recovery/deploying-exchange-2007-sp1-ccr-cluster-windows-server-2008-failover-cluster-part1.htmlregards,Mumin CICEK | Exchange - MVP | www.cozumpark.com | www.mumincicek.com
