This week I found a new to me issue with doing a database attach upgrade from 2007 to 2010. It seems if your 2007 content database has additional wildcard managed paths (anything other than /sites) that when you upgrade that database to SharePoint 2010 that you will end up with a bunch of explicit managed paths in SharePoint 2010. Kind of break downs like this:
2007 Wildcard managed paths:
2007 site collections in the content database:
When you create a new 2010 web application and attach the content database you will get the following managed paths:
- /sites – wildcard
- /departments/hr – explicit
- /departments/accounting – explicit
- /projects/CowMachine – explicit
- /projects/CowNinja – explicit
And of course all of your site collections will be available.
As you can quickly tell this is way less than ideal. For one when you try to create a new site collection for the Cow Black Ops project you will not be able to create it at /projects/BlackOpsCows because there is no longer a managed path for /projects. Boo! So how do you fix it? About time you asked.
Create managed paths before attaching 2007 content databases
The fix here is quite simple. Know your managed paths you need before you do your upgrade. Then right after you create the 2010 web application and before you do the mount-spcontentdatabase you need to go into Central Admin > Web Application management, click your web application and then from the ribbon select managed paths. Now create your wildcard manage paths. In this example you create /departments and /projects. Now return to your regularly scheduled program and do your 2007 content database upgrade.
If you already find yourself with this issue the fix is as simple as you are assuming. Go into central admin > manage content databases and remove your upgraded databases. Once they are detached go delete all of the explicit managed paths for your database. Then create the wild card paths you want. Now reattach your content database. All better. J
Hope this helps
