Upgrading from WSS 2.0 to 3.0

Microsoft provides three approaches for upgrading from WSS 2.0 to WSS 3.0. More here.

If you are installing WSS 3.0 on a different server than the existing WSS 2.0, the only approach available is the “Database Migration”. This approach is considered "advanced" and requires additional steps. If you have a WSS 2.0 that has not been customized, this seems likes overkill for such a simple upgrade.


The following approach lets WSS do some of the behind the scenes work for you. This approach has WSS 3.0 creating the files needed for a new Web application and configuring IIS.


SUMMARY: 


  • Using Central Administration, create a new Web application in WSS 3.0 

    • Create with all of the “production” values desired EXCEPT create a temporary content database. 

  • Using STSADM, attach the V2 content (which WSS 3.0 will upgrade to V3) . 

  • Using Central Administration, remove the temporary database. 


DETAILS:



  • Install WSS 3.0 on the new server (if you have not already done so)

  • Copy the WSS 2.0 content database to the database you wish to use for 3.0

    • (copy MyContent2 to MyContent3). 

  • Using WSS 3.0 Application Management:

    • Create a new Web Application         

      • Create new IIS Web site with a temporary database

      • Database Name : wss_Portal_Temp (this database will be deleted, you must use a name of a database that does not already exist when creating a new Web application) 

  • Attaching content from WSS v2

    • Verify the SetupService account is a dbowner for the  MyContent3  database

    • Run stsadm

      • stsadm –o addcontentdb –url http://wss/ -databaseserver MyWSSServerName –databasename MyContent3

      • This might run a while if you have a large database

    • Review log file: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\LOGS\Upgrade.log

    • Review the Application event log on the WSS 3.0 server

  • Using WSS 3.0 Central Administration remove the temporary database

    • Application Management tab

    • SharePoint Web Application Management section

    • Content Databases Link

    • In the “Manage Content Databases”

      • Select desired web application in the Web Application dropdown

      • Click the link for the Temporary Database

      • In the “Manage Content Database Settings”

        • scroll to the last section and check “Remove Content Database”

        • Click “OK”
