New Lab Migration–Part 3

The last server in this little lab of mine is the Exchange server. To recap, my network now looks like:

  • DC1 running Windows 2012
  • DC2 running Windows 2012
    • AD forest/domain at Win2012 functional level
  • FS1 running Windows 2012
  • EXCH1 running Windows 2008 and Exchange 2010

Like the other servers, I install the Windows 2012 disk and run setup

  • Insert Windows 2012 setup DVD
  • /setup.exe
    • “Install now”
    • Go online to install updates as needed
    • Product key
    • Select OS type to install
    • Accept license terms
    • “Upgrade”
    • Compatibility report
    • GO!
    • A few reboots… This one is taking WAY longer than the others… Making me nervous.
    • It FINALLY finished!

It looks like the update worked. But, while waiting for this to finish, I did some research. It looks like early versions of Exchange 2010 don’t play nicely with Windows 2012. I am actually surprised that the lab Exchange server didn’t blow up when I upgraded the OS on it… From what I have read, I am surprised it is working. In either case, I will make sure that my production Exchange server is current with all updates before running the OS upgrade. Exchange 2010 SP3 and later seems to work fine with Windows 2012.

This has been a good lab. I am confident that these upgrades will go well on my production systems. I have already run the checks (listed in Part 1) and my AD/replication/etc. all look good.

Ready to go!

New Lab Migration–Part 2

We have successfully upgraded our DCs. So, the network now looks like:

  • DC1 running Windows 2012
  • DC2 running Windows 2012
    • AD raised to Windows 2012 functional level
  • FS1 running Windows 2008R2
  • EXCH1 running Windows 2008R2
  • CLIENT1 running Windows 7

I know want to run an in-place upgrade on the file server. I am just going to put the disk in and run setup.exe

  • Insert Windows 2012 setup disk
  • run /setup.exe
    • “Install Now”
    • Go online and install updates as needed
    • Enter license key
    • Pick OS type to install
    • Accept license terms
    • ‘Upgrade’
    • Warnings/Compatibility report
    • GO!
    • Reboots, etc.
    • Done.
    • Add Dedupe Role feature
      • File and Storage Services Role
        • File and iSCSI Services
          • Data Deduplication
  • Enable Dedupe on data volumes
    • File and Storage Services
      • Volumes
        • Disks
          • Select the data disk
          • Under volumes, right click on volume and select “Configure Data Deduplication”
            • Enable Data Dedupe
            • Configure
  • Wanted to test something I read about, some people having problems accessing network shares on Windows 2012 servers if the disk/volume is added after server is joined to domain
    • Create new VHD and attach to FS1
    • Set up disk
    • Create the folders/shares
    • Test access from client computer
      • No problems accessing shares/files/folders on new volume. Good news.
  • I set the dedupe aging to 1 day. I also copied a file over an over. Hopefully, it will dedupe and I can see the numbers.

So far, everything is working well. Now, to see about upgrading the Exchange server.

New Lab Migration–Part 1

I outlined here a new lab that I am running. My goal is to test in-place upgrades from Win08 to Win12 on DCs, File servers, and Exchange2010 servers.

My first step is to upgrade the DCs.

To review, the current lab network consists of:

  • DC1 running Win08R2
    • Running AD, DNS, DHCP
  • DC2 running Win08R2
    • Running AD, DNS
  • FS1 running Win08R2
    • Various shares, files, ACLs, etc.
  • EXCH1 running  WIN08R2 and Exchange 2010
  • CLIENT1 running Win7

So, my first step is going to be upgrading the DCs and domain to Windows 2012. I will be following the steps I outlined in this post. Should be pretty straightforward.

First, run a couple of test tools to see if anything looks horrible.

  • Dcdiag /v /c /d /e /s:DCName >c:\dcdiag.log [please replace DCName with your Domain Controller name]
  • Repadmin /showrepl dc* /verbose /all /intersite >c:\repl.log ["dc* is a place holder for the starting name of the DCs if they all begin the same (if more than one DC exists)]
    • These are taken from here.

Then…

  • On DC1
    • AD Sites and Services to force replication
    • Start command prompt as Administrator
      • from Windows2012 install disk
        • \support\adprep\adprep /forestprep
        • \support\adprep\adprep /domainprep
        • \setup.exe
          • Go online and get updates as needed
          • Enter product key
          • Select OS to install (core, w/GUI, etc.)
          • Accept license terms
          • ‘Upgrade’
          • Warnings?
          • GO!
          • Automatic reboot
          • More GO!
          • A couple more reboots…
          • All Done!
    • Verify services and everything looks OK.
  • Reboot Mail server
    • Looks like it needs the new schema info
  • Reboot file server
    • For good measure
  • Test client connectivity, services, etc.
  • On DC2
    • from Windows2012 install disk
      • run \setup.exe
        • Go online and get updates as needed
        • Enter product key
        • Select OS to install
        • Accept license terms
        • ‘Upgrade’
        • Warnings?
        • GO!
        • Etc. Etc.
        • All Done!
  • Force replication between DCs
  • AD Domains and Trusts
    • Right-click on AD Domains and Trusts
      • Raise Forest functional level

Everything seems to have worked as advertised in the lab! I know have two Windows 2012 DCs with a Windows 2012 forest/domain.

Now, on to the file server upgrade.

More Testing

I am back in my lab, doing some more testing. I have decided that this is the year to get off of Win08 and move everything I can to Win2012. To that end, I am building a lab that replicates our production environment and am going to do some upgrade/migration testing. Specifically, I want to test (and perhaps re-test):

  • Windows08R2 AD upgrade to Windows 2012 AD
  • An existing file server, running Windows08, upgrade to Windows2012
  • An existing Exchange2010 server, running on Windows08, upgrade to Windows2012

My plan is to do these three upgrade in this order.

My starting environment will look like this:

  • DC1 running Win08R2
    • Running AD, DNS, DHCP
  • DC2 running Win08R2
    • Running AD, DNS
  • FS1 running Win08R2
    • Various shares, files, ACLs, etc.
  • EXCH1 running  WIN08R2 and Exchange 2010
  • CLIENT1 running Win7

All of these machines will be part of the AD domain. My plan is to test in-place upgrade of the OS for all of these servers, in the order listed.

We will see how it goes. Stay tuned.
