Migrating from Exchange 2007 to Exchange 2013

I have successfully installed Exchange 2013.  I am trying to minimize any issues with this migration.  Can someone direct me in details on what I need to do next and how.  I just need to decommission Exchange 2007 by this weekend.   Please help me.
Thanks

I am unsure about Digital Certificates Configurations.  Not too sure about this.  Can someone explain this please

Submit your certificate request to be signed by your CA, then use the following command to import the certificate:

Do I need to export the certificates from my Exchange 2007 server.  And if I do, can you kindly explain.

Thx

Zubby,

You have two options:
1. Going through the co-existence scenario which requires configuring and using a legacy namespace, and requesting and installing a new UCC (Multiple Domain Certificate) on both Exchange servers.
2. Going through the quick upgrade scenario. (not recommended, especially for the Exchange 2013 upgrade).

It seems that you are planning to choose the second option. Normally, this means that you are perfectly clear about the individual steps and the whole upgrade is pretested in a lab.

Anyway, the straight answer to your question is that if you are going with the quick upgrade scenario and you already have a valid trusted UCC on the Exchange 2007 server, you have to export it to a PFX file and import it in Exchange 2013. No need to request a new certificate.

It seems the the cert was issue by the Exchange 2007 Server.  Do I still need to export it to the Exchange 2013 Server.  And also I am seeing multiple certs, which one do I need to export if I need export.

Thanks
