DR Failover for Exchnage Hybrid Server 2010

Hello,
I have a question regarding DR failover for Exchange 2010 Hybrid server and 2007 in the coexistence scenario with 2007 Exchange Servers and office 365.

Mailflow is coming to onprem first to 2007 servers using MX records, then it goes through the hybrid server through the send connector to O365.

I already setup second Hybrid Server 2010 SP3 in the DR site. Please let me know if I am missing anything from my list and what else I need to worry when we will be doing the switch?  We will lose the power to the primary center and we need to switch everything to the DR center and make sure that mailflow is still working.

Here is the checklist I used to setup Hybrid server in the DR site


-Installed Exchange 2010 SP3
-Exported cert and assigned services (SMTP and IIS) to the certificate.
-Binded certificate to the IIS website
-Setup Web Services URLs (AutodiscoverURI, EWS, ActiveSync, ECP, OAB, etc)
- Exported the configurations of the Office 365 Receive connector to the DR Hybrid server

Please let me know the additional steps I need to perform to make sure mailflow doest stop.
Thanks a lot

You'll want to read an article like this - http://www.msexchange.org/articles-tutorials/exchange-server-2010/management-administration/planning-deploying-testing-exchange-2010-site-resilient-solution-sized-medium-organization-part9.html

Failing over with 2007 servers in the mix will be a bit wonky. You really should have all the same server type unless your 2007 servers are just Edge Gateways or something of that nature. You'll need a DAG and utilize DAC for this to work properly and allow you to reseed your failover back to the main site.
