Migration from Sharepoint 2007

End of Windows 2003 extended support is reaching fast, if you are not migrated away, this is the last chance! Migrating from Sharepoint 2007 is I guess a bit tricky; but if you break it down into little steps; its manageable…

Typical Sharepoint 2007 deployments are Windows 2003 32bit / SQL 2005; I would suggest to first move to Sharepoint 2010 on Windows 2008 R2 64bit / SQL 2008 R2 and then to something more recent. You will get introduced to x64 based Server Environment, next gen IIS / Management Consoles from Microsoft. Sharepoint 2010 is also bit more expanded and getting hold of all these things take some time. Secondly there’s tons of information available for upgrading to Sharepoint 2010 and chances of getting stuck is very less. This step is also most crucial due to x86 to x64 migration and the most easiest way is I guess using the database attach upgrade. This approach involves setting up a Sharepoint 2010 separately and then taking a content backup from the Sharepoint 2007 farm and attaching it to your separate Sharepoint 2010 farm and then upgrading it, both systems remain separate and you can do the tweaking and testing without any pressure from the end users. The other two options are in-place upgrade and hybrid upgrade and you can read about all these options on TECHNET and decide yourself what suites you most.

All in all; Database Attach Upgrade approach involves

  • Installing / Configuring and Building the new Sharepoint 2010 farm usually on Windows 2008 R2 / SQL 2008 R2
  • Creating a new Web Application and associated Site Collection in Sharepoint
  • Detach the default content databases that gets created in the previous step; you may delete it all together
  • Getting ready your Sharepoint 2010 for upgrade; it involves installing / activating some additional features; this is done from the PowerShell (another new thing you might have to learn if this is your first time with Sharepoint 2010 / Windows 2008 etc)
  • Restoring the content database of your Sharepoint 2007 site collection
  • Attaching this restored database as the content database of the newly created Web Application / Site Collection in Sharepoint 2010;
  • Upgrading the content databases

After this you might have to upgrade and deploy your custom ASPX / Workflows and other custom coded things into the Sharepoint 2010; this might take some time and this is why I am recommending this approach as it involves some patience and lots of testing you can do that on your own pace without any pressure from the end users. Once you are good to go; you can re-do the above upgrade steps one last time setting up a “Production Site Collection” for the final upgrade

Step by step instructions and commands for this approach are available on http://www.orcsweb.com/blog/cory-granata/sharepoint2k7-to-2k10-migration-using-db-attach-method and http://www.sharepointdiary.com/2011/09/migrate-from-moss-2007-to-sharepoint-2010.html
