Hi forum members,One of my customer having Exchange 2007 with Roles HT,CAS,MBX installed. They wants toimplement anExchange 2007 clustering and they need to perform amigration from existingexchange 2k7 intonew exchange 2K7 cluster setup. And they ask us to create new exchange organization for Exchange clustering and migrate from an existing organization. Currently they are having Only one Windows 2003forest which contains only one domain. So what is my question is , Is it possible to create new Exchange organization in forest which already havingan OneExchange organization? If it is not possible means then how to setup Exchange 2007 clustering with Existing organization and perform a migration from Existing Server to New Exchange Clustering?Please help me...Very Urgent....Saravanan

No, one AD forest can have only one Exchange Organization. But what's the reason creating new Exchange org? You can create a new AD forest, move all users and group to new AD forest with ADMT. Implement Exchange 2007 Hub and CAS and Mailbox server role in clustering as per the link given in your another thread and move all mailbox across the forest...

But doesn't make any sense to me to change/recreate the Exchange organization, so still same question what's the reason behind org recreation?Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com
