Transitioning from Exchange 2003 to Exchange 2007

Question

I have both servers up and running now. Only my mailbox has been moved to the new Exchange server. It does seem, however, that my mailbox is continuing to get archived (even though I have done nothing!), because i can search the archive for even my most recent message. Maybe someone can explain that one, because I haven't configured journaling on the new 2007 info-store that my mailbox currently resides on (hmmm...). Is this due to the connector between exchange servers? Anyway, my real question is in how to go about this transition. Should I simply move the journal mailbox to Exchange07, set send-as, recieve-as perms on Exchange07, and make sure journaling is confiured on the new stores (even though, as by my previous comment, that just doesn't seem to matter)? Or do I create ANOTHER journaling account on Exchange07, set send-as, receive-as perms, make sure journaling is set to this account on the new stores, also make sure that this new journaling account is configured on the EmailXtender server, AND THEN FINALLY move mailboxes over to the new stores one by one?

Hi Oscar,If it would be me I will start journaling to mailbox on Exchange 2007 because that envelope journaling enabled. More information on this should be in EX guides.Secondly if you are in doubt I would suggest engaging professional services who have done it at other sites so that could help you with this one without you facing any issues.Hope this helps.Thanks,Raj

Hi Oscar,I've replied to another post with a similar theme, so I thought I'd repost here to help you along.+++++++++++++++++++++++++++++++Comments from other post start here:+++++++++++++++++++++++++++++++My response might be a little late, but I thought I'd at least post my experiences to help future migrators that come across this thread. I'm currently going through the migration process myself, but have completed most of the steps.Yes - there are things you need to pay attention too. First of all, EMC provides little to no documentation on how to do a step-by-step migration from an existing Exchange 2003 environment to an Exchange 2007 environment, not even in the most general sense. I've read the Release Notes document for 4.81.1147. It takes about setting some things up for Exchange 2007, but does not cover a 'best practice' for keeping EmailXtender services running while migrating between 2003 to 2007, which is what many people are asking about.Also, to clarify on other Exchange 2007 deployment comments, you do not upgrade an Exchange 2003 server to 2007. There is no upgrade path. You can only MIGRATE from Exchange 2003 to 2007. This means you setup a new Exchange 2007 server to temporarily coincide with your existing Exchange 2003 servers. It's actually pretty easy, is well documented from several sources on the internet, and the Exchange 2007 setup does most of the work to 'bring itself' into your exisiting Exchange environment.My environment consists of:- (1) Exchange 2003 server- (1) EmailXtender server running 4.81.1147- (1) Exchange 2007 serverFollowing Microsoft's guides, setup your Exchange 2007 to coincide with your existing Exchange 2003 server. Setup a test mailbox on Exhange 2007 or migrate your own account over using the Exchange 2007 mailbox migration tool. Test your email flow between mailboxes on 03 and 07 as well as to and from the internet.Create a new account/mailbox on Exchange 2007. Call it EXADMIN07 or similar to easily identify it. Open the Exchange Management Shell and run the following two commands to give it RECEIVE AS and SEND AS permissions:Add-ADPermission -identity (get-mailboxserver -identity 'Exchange 2007 Server Name' | select-object).DistinguishedName -user 'DomainName\exadmin07' -ExtendedRights Receive-AsAdd-ADPermission -identity (get-mailboxserver -identity 'Exchange 2007 Server Name' | select-object).DistinguishedName -user 'DomainName\exadmin07' -ExtendedRights Send-AsIn the above two commands, replace 'Exchange 2007 Server Name' with your actual server name. Be sure to leave the quotes. For 'DomainName\exadmin07' you can specify just the username of the new exadmin account (exadmin07) if you only have one domain. Again, leave the quotes.As a side note, according to the installation guide, on page 6-12 it suggests giving the EX account full access by running the following command:add-mailboxpermission 'mailbox-name' -user 'EX-account' -accessrights fullaccessThis works too, but I didn't find it necessary.Next, we need to give the original EXADMIN account (whose mailbox is probably stored on the Exchange 2003 server) the same permissions on the Exchange 2007 server. Therefore, run the following two commands from the Exchange 2007 Management Shell:Add-ADPermission -identity (get-mailboxserver -identity 'Exchange 2007 Server Name' | select-object).DistinguishedName -user 'DomainName\exadmin' -ExtendedRights Receive-AsAdd-ADPermission -identity (get-mailboxserver -identity 'Exchange 2007 Server Name' | select-object).DistinguishedName -user 'DomainName\exadmin' -ExtendedRights Send-AsThe above two commands assume the EX account on the Exchange 2003 server is called exadmin.Next we need to start journaling Exchange 2007 email:Open the Exchange Management Console.Navigate to Server Configuration -> MailboxRight-click your main Exchange 2007 mailbox database and choose PropertiesCheck the box next to 'Journal Recipient'Click the Browse button and add the EXADMIN07 account.Click Ok.Now, go to the EmailExtender server and add the new mailbox to pull journaled mail from: Open EmailExtender Administrator. Login. Open the server tree in the left pane. Right-click 'EmailVault' and choose Properties. Click the Email Connection Mailboxes tab. Click the 'Add Exchange Mailbox' button at the bottom.Browse for the EXADMIN07 mailbox and click Ok.Click Ok on the warning that you need to activate changes.Click Options -> Activate Changes.Click Yes on the warning that it will disrupt ongoing searches.I have Outlook 2003 installed on my EmailXtender server. I configured the mail profile to monitor the EXADMIN07 inbox along side the EXADMIN inbox. This way you can watch email being journaled by both Exchange servers and watch email being pulled correctly from both mailboxes too.Open Outlook on the EmailXtender server.Click Tools - Email AccountsClick Next.Click Change to edit the Exchange Server settingsClick More SettingsClick the Advanced tabClick AddType EXADMIN07 as the mailbox nameMake sure you are NOT using Exchange cached mode (the checkbox should not be checked)Click OKClick NextClick Finish.Scroll down on the left in Outlook and you should be able to open the plus sign next to 'Mailbox - exadmin07' and view the inbox.Watch both inboxes. Send a few test messages to and from a mailbox on the Exchange 2007 server. Make sure they appear in the inbox using Outlook on the EmailXtender server. What a few moments and they should disappear as EmailXtender collects the messages. If they don't disappear after a minute or so, either stop and restart the EmailXtender services or reboot the EmailXtender server.After all mailboxes are migrated to the Exchange 2007 server and Exchange 2003 has been properly decommissioned and uninstalled (as per Microsoft documention), you can delete the exadmin account and remove it from the list of monitored mailboxes in EmailXtender Administrator.I'm up to the point now of trying to figure out how to properly deploy the ExShortcutPost.oft and ExShortcut.oft Outlook form templates to my Outlook clients so that shortcutted email attachments work properly. Right now they don't because Exchange 2007 doesn't use public folder templates like things were setup in the Exchange 2003 environment. So, each machine needs these OFT files physically installed. Again EMC's documentation is poor in this area. They just say 'Push out and publish the OFT files to the Personal Forms Library on each Outlook client', but they don't actually explain how to do this.Lastly OWA shortcut support will be an issue in Exchange 2007. The installation manual says 'Not available in this release' (section 6-34), yet casual phone conversations with EMC tech support says it is. I don't know what to believe.I really wish EMC would take a few moments to pull together a document describing some of the migration scenarios and how to do them. After all, it's their properietary software on only they know how it works. Microsoft has good documentation on how to migrate from Exchange 2003 to Exchange 2007, so why can't EMC do the same with EmailXtender?I'll post back more comments as I figure out the rest of the OFT and OWA stuff, but I'd appreciate any help too.
