The Windows Small Business Server 2011 Standard Migration Preparation Tool is included in the Windows Small Business Server 2011 Standard installation media. This tool is run on the migration source server (for example, a computer that is running Windows Small Business Server 2003 or Windows Small Business Server 2008) to prepare the source server for migration. This tool performs the following tasks on the source server:
This update is a critical step in helping prevent known causes that can lead to a failure during the migration setup.
To get the latest set of rules, when you launch the tool, select the option to check for updates.
For details check the following article: 2578426: An update for the Windows Small Business Server 2011 Standard Migration Preparation Tool is available
For the out of box existing rules check the following article: 2481235: List of rules for the Windows Small Business Server Migration Preparation Tool
You might hit Sub Rule 7 from the update (KB 2578426) unexpectedly.
Rule: Error is found in DNS Zone [DNS zone name] Severity: Error Description: DNS zone [DNS zone name] does not exist. Migration will fail without fixing this issue. Go to http://support.microsoft.com/kb/2578426 for more details.There are 2 causes that can lead to this unexpected error besides the issues discussed in the KB article.
if your _MSDCS zone is not a forward lookup zone delegated from your primary domain zone. you may see the error.
The check expects your _MSDCS zone to be delegated like this:
If your _MSDCS is a subdomain (see screenshot below), then the check will fail.
You will have to remove the _MSDCS subdomain, create a new AD integrated forward lookup zone for _MDCS.domain.local (replace domain.local with the name of your domain), and finally create a delegation for _MSDCS under your domain.local primary lookup zone pointing back to the name servers in your domain (your own server only in most SBS networks). Restart the netlogon service, confirm that the new _MSDCS zone gets populated.
This is a known issue and a long term resolution is being investigated.
If the microsoftDNS namespace is missing from the WMI repository this query will fail. To test this open a Powershell command prompt as an administrator and run the following command:
Get-wmiobject –namespace root\MicrosoftDNS –class “MicrosoftDNS_Zone”
If you have this issue you will get an Get-WmiObject : Invalid namespace error.
Use the following steps to resolve this issue.
Is this process of creating the proper _msdcs zone necessary only when migrating to an SBS 2011 platform? I am asking because I am in the process of migrating a client from SBS 2003 to standard Server 2008R2 without SBS and without Exchange. We will be converting to a hosted Exchange platform. I guess this brings up one more question. If I no longer have an on-premesis Exchange server, will I need to purge the schema of Exchange extensions?
I've found a bug in this update ...
It was reporting an error that my local server was not in the NS records for the intenal zone, however the NS record was correct. My internal zone is named in.domain.com, not domain.local - don't know if that makes any difference. I could not get past the error as there was nothing to fix: zone was AD integrated and secure updates only and the sole NS record was the FQDN of my server - server.in.domain.com. The only way I could proceed was to uninstall the migration preparation tool then install it again from the DVD this time choosing not to install updates.
Since you are migrating out of SBS there is no need to run the migration preparation tool. The schema should not be a problem.
Was _MSDCS its own forward lookup zone or a subdomain under in.domain.com ? If it was its own forward lookup zone, was there a delegation for _MSDCS under the in.domain.com zone? and if so, did it contain NS records?
