Migrating from SBS 2008 to dual servers


I have one sbs 2008 server and wish to migrate to two 2012 standard servers. The servers have been purchased and are onsite now. One will be my file server and the other will be exchange. My question is what would be the best way to go about this?
I have joined one server to the domain so far but thought I would stop and look into it some more.  Any help would be great thanks!

exchange SP1 is the same as CU4 so it is a little old

yes it is recommended to have at least 2 domain controllers for redundancy but installing exchange on the same box is not the way to go
the exchange setup will take care of any schema extension (provided you are logged on with the proper rights)

not sure what kind of hardware you are working with but you could have one physical domain controller also as a file server and one hyper-v server with exchange, and second domain controller both as virtualized guests

otherwise, you would be looking at another physical box to have that second domain controller - which shouldn't be a big expense with the low hardware requirements

if that isn't an option, make sure you have good backups of your domain controller

One will be my file server and the other will be exchange.

ok...will the file server become the domain controller?
what version of exchange?
2012 or 2012 R2?  will make a difference as far as exchange is concerned

The file server will become the DC and exchange 2012 (not R2)
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

what version of exchange are you planning to move to?
you are good for either 2010 SP3 or 2013

Exchange 2013. I already started the download. So far I made my file server a DC and moved all of my data files to that server and pointed all of my mapped drives to that server. Now I just need to know how to proceed with the second new server. Do I add it as a DC controller and then install exchange?
Seth SimmonsSr. Systems AdministratorCommented:
you can also promote your 2012 server to a domain controller; just don't move FSMO roles yet as that will put the SBS server in a 21 day grace period.  you want to save that as one of the last steps - give time for the exchange migration

you can use native tools for your file server and DHCP

ok so you got your files done
for exchange, do not make the second server a domain controller (not recommended and likely to cause issues); the file server is what you mentioned before which is fine

Installing Exchange on a domain controller is not recommended

also, which exchange download are you getting?
CU8 is the latest; you don't need the RTM or SP1 versions to install first.  you can go directly with this download

Cumulative Update 8 for Exchange Server 2013

The download from Microsoft Volume Licensing Center is Exchange 2013 Standard Service Pack 1. I also started to download the it from the link you sent me. Just to clarify, Do I need to do anything other to the exchange server other that just joining the domain? I thought maybe it could be my backup domain controller or handle DNS in case my PDC crashed.

Thank you for your help! really appreciate it!

Did you buy two servers and two server licenses?  If so, you probably just wasted $2000+.  A good consultant could have saved you that money.

A single server with sufficient RAM, disk, and CPU could easily handle two virtual machines (which ONE server license gives you).  

Don't forget to implement Shadow Copies, and the Essentials Role.

And don't setup two DCs unless you understand how to restore them when they fail.  

I hope you're installing these systems wisely - a TEST/LEARNING environment first -- TWICE -- and then your production environment.  It's incredibly unwise for someone inexperienced in the process and options to be doing this DIRECTLY on a production system without first learning it on a TEST system.

I would suggest before you go any further and potentially set things up inappropriately, it would be better to hire a professional to perform the installation if any of the above doesn't make sense to you.  Getting it done right the first time will give you the best possible experience... doing it wrong can cause problems for years!
