So for various licensing, network, etc. I need to do a Exchange 2007 to Exchange 2010 Migration. The exchange 2007 is the only Exchange server in the enterprise. The Exchange 2010 will also be the server in the environment.

Both server are VM and the 2007 server is running on WS2K8. The Exchange 2010 will run on a W2K12 server. Both are not R2 releases. The Exchange 2010 server has 48 GB RAM, and 8 Cores.  There are a total of 80 users in the environment.

At this point the Exchange 2010 server has been setup and patched, but Exchange 2010 has not been installed yet, Going to do that sometime this week.

Does anyone have any good guides or words of wisdom to share.

Why not transition to Exchange 2013 from 2007, instead of to Exchange 2010?

Since Exchange 2010, Microsoft has recommended nothing but multi-role for Exchange servers.

Do not, DO NOT, disable IPv6 on any NICs in the Exchange server.

Initial/max paging file size must be amount of RAM + 10 MB.  With a max of 32GB paging file size with Exchange 2013 and 2016.
