Hello,
We have an upcoming migration that i'm trying to plan for. My appologies in advance as I am new to this job/environment, i did not create this setup. I hope I've included all pertinent information.
Current Environment
Clustered
MBX01 - Exch 07 MB role (03 Enterprise)
MBX02 - Exch 07 MB role (03 Enterprise)
Not Clustered
CAS01 - Exch 07 CA role (03 Enterprise)
HUB01 - Exch 07 HT role (03 Enterprise)
UM01 - Exch 07 Um role (08 Standard SP2)
Lync
LYNC00 - Lync Server 2010 (08 R2 Standard) - IIS role
LYNCMON - Lync Server 2010 (08 R2 Standard)
Lync is integrated with exchange, though I can honestly say i'm not exactly sure what services each of those servers are providing. I believe LYNC00 is the 'main' out of the two.
Target Environment
EX01 - (Server 12 R2 Standard)
EX02 - (Server 12 R2 Standard)
Short version (from what i understand) : current environment is 07 exchange, high availability with Lync. new environment is a pair of 2012 servers, that will need to be exchange 2013 High Availability and Lync Integration. These will need to be run in Coexistence mode initially. I believe there are about 650 accounts, no public folders, 50ish calendars.
I've referenced two books (Mastering Exchange 2013, and Pro Exchange Server 2013 Administration), researched the best i can online. However; Coexistence, HA, and the migration itself are all new to me. I'm familiar with the install and setup of one exchange server, and all of the administration that is done with an exchange server, but not so much with the new environment that I am now in. What would be the best way to go about this? I need to create a plan for this migration, and then naturally use said plan to perform the actual migration. I may indeed have all of the information i need, but i do not feel all that confident in creating a plan for something i'm not very familiar with, then implementing that 'best guess' of a plan.
any advice is appreciated :)
