Upgrading from 2007 to a 2010 Multi tenant environment

Question

I have been looking around and havent found any guidance on upgrading from a 2007 farm to a multi tennant subscription based 2010 farm.

I this a significantly different process than the normal migration? I am unsure how to proceed and how would the migrated sites be aligned to a particular subscription post migration.

Thanks,

Anuj

Answer 1

All details about migration are here: http://technet.microsoft.com/en-us/sharepoint/ee517214.aspx

You must assure that all steps are done. It is not just update setup, next, finish. It is an entire process, but from y experience all portals were sucesfully migrated, checking stept by step from the article reffered.

Good luck!

Thanks for the reply Valy. 

I understand the upgrade process. The important bit here is the "Multi tennant environment". The upgrade process has no scenarios dealing with the same.

Can anyone point me to a resource dealing with such a case.

Thanks,

Answer 3

Anuj, it is almost the same process! If you have resources deploy first a multi farm into a test environment and after that do the migration steps to asuse the success of your operation.

Thanks Valy.

Some details below on my confusion with the process

We currently have a 2007 farm with several web applications. We plan to move to a new 2010 farm which will be shared with other country units.

The new farm will have a multi tenancy partitioned model with each country unit having one subscription ID under the same web application. The farm will be set up in the multi tenancy model as described here http://www.harbar.net/articles/sp2010mt1.aspx

If a database is attached to the new farm, the upgrade process runs and the sites are moved to the web application on the new farm. They retain their url’s etc .

How would the sites migrated be aligned to a particular country units subscription. This may just be a PowerShell command, but I don’t know it yet.

Answer 5

Anuj, did you run pre-upgrade checker  http://technet.microsoft.com/library/cc262231(office.14).aspx on your environment? There will be a detailed report if your deployment is ready to be upgraded. There is not important how many web app do you have on your deployment.

Valy,

You are missing a critical point here- The target farm is a multi tenancy farm and the sites need to be migrated to one particular subsciption

Hope this makes sense.

Thanks,

Fundamentally this is not a scenario the standard approaches to upgrade can or have been designed to handle.

There was of course no multi tenancy in SharePoint 2007.

None of your shared services data can be migrated to partition mode Service Applications in 2010. There is no way to migrate data from the SSP DB to partition mode Service Application DBs from the upgrade process.

Similarly, Site Collections. However these are a little easier to deal with as you can upgrade the site collections and then add them to a Site Subscription. Thus they then become multi tenant in that respect.

However it's the shared services data you will need to deal with. You will either need to recreate the data, or do manual and painful scripted data migration. The former being the much better option.

Thanks a lot Spence for clearing this up.

Not bothered about the shared stuff, we are planning to leave them behind. Any chance you could guide me on how to add a site to a site subscription. I am assuming this must be a PS command or cmdlet but have drawn a blank so far.

Once again thanks for your help.

Answer 9

Yup, you have to add the site to a subscription via Windows PowerShell

$subid = Get-SPSiteSubcription <GUID_OF_SUBSCRIPTION> 
$site = Get-SPSite "http://siteurl"

Set-SPSite -Identity $site -SiteSubscription $subid
