-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Niles Ferrier Sent: Monday, January 30, 2006 3:39 PM To: Exchange Discussions Subject: Best Practice/Tips and Tricks - Migrating from 5.5 to 2003 Hi All, We are going to be moving from Exchange 5.5 to 2003 (finally) and I would like to try my best to get it right the first time. I have been involved with a bad migration on a similar scale to what I am about to start here, which gave me a good idea of how the whole process works, and what to look out for this time. Basically this is a simple setup. A mixed NT4/2003 domain, a single site, single server, exchange enviroment, and all servers are in the same building (so no lengthly delays for domain/forestprep). My main concern is creating hundreds of dummy accounts in AD because the ADC cant match a mailbox to an AD account. So I would like to do what I can to avoid that happening. I know that a user cant be primary account in more then one mailbox, nor can a group be the primary account of a mailbox, so I will fix these things in Exchange 5.5 before starting anything, but beyond this, what other things can I do to ensure good match up between Exchange 5.5 directory and Active Directory? Some things I would like to find out are: - How does ADC match mailboxes to accounts. The last attempt I saw, new AD accounts were created for ALL mailboxes. Does it use the alias and account name, SID, etc..? >>> Primary Windows NT Account's SID. If the SID of the Primary Windows NT Account exists in the target domain, whether it's the primary account SID or there by SID history, that account is matched and no new account is created. - When ADC does match mailboxes to accounts, I assume that in AD Users and Computers, I will see some form of Exchange attribute on the user account who has been matched with a 5.5 mailbox (similar to a user who has an exchange 2003 mailbox)? >>> That account will become mailbox-enabled and the store will show as being on an Exchange 5.5 server. - Is it good practice to create a new OU for unmatched mailboxes/accounts in AD.. For the sake of keeping them seperate in the event that they are created? >>> Yes. - Any other advice? >>> Don't fret over the disabled account creation. It's normal and necessary. >>> Use the ADC Tools feature of Exchange 2003 to preview what ADC will do and resolve your mailboxes' Primary Windows NT Accounts. Try to make it so that each mailbox has a unique Primary Windows NT Account and then you shouldn't have any surprises. >>> Check the "Deletion" tab on your connection agreement. Be aware that if you want to start over, and you delete all the newly-created disabled accounts, the default setting on this tab will cause all the mailboxes to be deleted. Likewise, if there are any good migration guides on the web besides those on Microsoft, please let me know. Many thanks for your expertise. Cheers. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
