I have a few questions.
We currently have a single Exchange Server with all roles running on it. It is an Exchange 2010 environment with over 3000 mailboxes, and is backed up daily.
We would like to move to the new Exchange 2013 and implement it with the DAG solution.
I understand creating the the first 2013 Exchange and bringing it into the current environment so I can migrate mailboxes over. However, I am lost on the best way to bring the second 2013 in to set the DAG.
Should I build both 2013 servers and bring to the current 2010 environment, migrate the data, decommission the old 2010 environment and then set the DAG?
Should I bring only one 2013 server over, migrate data, decommission the 2010, then bring the second 2013 online and implement the DAG?
I am looking for the best "documented" solution to allow inline migration of data, smooth transition out of 2010 without email being offline, and a DAG implementation.
The DAG will be setup with each server having two LUNs that will be kept on separate data sources with an active/passive relationship.
Any guidance on the proper steps is deeply appreicated
