Migrate Windows 2008 R2/Exchange 2010 to SBS

All

Have a potential client that we are looking at to take on but they've a server that is currently running Windows 2008 R2 with Exchange 2010 on top - the server is a DC...

This was built by a college IT student...

Obviously its not a recommended setup so I want to know if there are options to fix it going forward

1) Can we migrate this setup to a SBS 2011 machine at all? If so any documents on the procedure we need to follow? Or anyone done this successfully before?

2) If that isn't an option can we build up another 2008 R2 machine and move Exchange to it? If so what's the best way to do this?

3) If neither is an option what should we do? Is this safe to work with as is?

Thanks for the help...

What is the problem?

SBS 2011 is Exchange 2010 on Windows 2008r2 as a DC, so you would be moving to exactly the same situation with SBS as you have now, so what is the point?

So you are saying this is ok and supported? Everywhere I look I see people saying this isn't recommended and because of that if something goes wrong it will be hard to fix etc...

I understand SBS is the same...but SBS has a lot under the hood that ties everything together and makes things work(wizards etc)...

Again if running this as it stands is ok then so be it...

How many users are we talking about?
You are correct in that it isn't recommended to put Exchange on a DC, and SBS is a special case after all. However if the client already has the software licences, why buy it all again for SBS 2011? If the user base is likely to grow then I would start to plan to spin Exchange off, perhaps on to another server with Windows 2012. Then use virtualisation so that you can have two additional machines, another domain controller and Exchange.

Thanks Simon...yes user count is 40 at minute...again they don't WANT SBS...its just they want to know what is the best plan to make sure this will stay up and running without any potential issues going forward...

I recommended virtualisation so that's fine

Is the process of building another 2008/2012 machine and installing Exchange and then migrating the existing mailboxes over simple? Sounds simple when I say it but just wanted to be sure before going back to them...

I assume I build the new machine(VM if necessary), install Ex2010, then perform a move mailbox to the new box?

Whilst not being recommended, it is possible and perfectly workable.

SBS does tie everything together nicely with Wizards, but that is more about management than providing extra security to make running Exchange on a DC much more secure.

You could always push mail to Office 365 and then remove Exchange from the DC so you are left with a single server running as a DC with mail in the cloud.  Better to have two DC's in case one fails, but that would either mean virtualisation or additional hardware, which they might not have the budget for.

At 40 users I wouldn't even consider SBS.

The major issue with moving the mailboxes it getting the clients to follow, as they will not automatically. Therefore make the changes now to ensure that future growth isn't an issue - specifically configure an RPC CAS Array if there isn't one already. You will have to visit each workstation to get them to use it, but that only has to happen once and can start before you move mailboxes.

Doing the actual move of data and settings is very easy because everything is stored in the domain. The number of settings you have to replicate on the new server from the old is pretty small.

Ok, well that's good news then...thanks Alan, did not know that...

Might leave well enough alone if that's the case

I'll give them options and see what they want overall...they started with SBS 2003 which is why it was mentioned...so they still might want to have that for management purposes but will wait and see

Cheers Simon and thanks for the assist...
