Either way you do it, the HTs will be intelligent enough to work it out. We changed our inbound to 2010 quite early on (using a smarthost that accepts mail from the internet). Again, the efficiencies of routing the mail should be your concern I think - if you don't mind an extra hop from 2010 > 2007 or vice-versa, you can either leave it as is or send all email to 2010 and have it send back to 2007.

One last though just came to mind. Inbound. Current flow is through a spam filter then to the 2007 HUB. I will need the 07 HUB to forward to the 2010 HUB for the '10 Mailboxes....is there a connector for that or is it smart enough to figure that out? I also could flip the spam filter to forward to the 2010 HUB right away if that is a better way to do it. Has to happen sooner or later anyway.

Remember for that to happen, you'll need to add your 2010 HT to the Send Connector. Essentially, your Send Connector will stay the same, so you can control which HT server(s) handle outbound mail by adding/removing them from the Source Server. It was more efficient for us to add the 2010 servers in and then it was exactly as you think. 2007 users went out via 2007; 2010 users went out via 2010.

Current setup is a single CAS/HUB and two mailbox servers all 2007. There is no edge. Incoming hits a spam appliance that feeds the hub. Outgoing is done with the hub. OWA is published through an ISA 2006. Seems pretty straightforward, put up a new CAS and set up the legacy system, add an ISA rule to publish the new CAS. Then add the first mailbox server and start moving. Where I am hung up in my planning is the Hub server. At some point the 2010 Hub needs to take over transport to the internet. My guess is it will take it over right away for the mailboxes that are on the 2010 Mailbox server and the 2007 Hub server will continue to handle the 2007 Mailboxes until they are all moved? Just want to be sure, I recall the 2007 upgrade from 2003 when that Hub server just took over right away. I wasn't prepared for that and it caused me undue stress getting rDNS set up and the firewall holes punched. --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
