TFS DB Transfer

HI,

we have requirement to change TFS Database server to other server. Application server remains the same.

Followed Following steps described in blog

http://blogs.msdn.com/b/tfssetup/archive/2014/05/15/migrating-team-foundation-server-databases.aspx#comments

we have Taken DB Backups from OLD server and restored In new server.

Executed following Command for Remapping the DB's below one is success

TFSConfig RemapDBs /DatabaseName:ServerName;DatabaseName/SQLInstances:ServerName1,ServerName2
[/AnalysisInstance:ServerName] [/AnalysisDatabaseName:DatabaseName]

Question 1:

Next Used following Below Syntax to change owners of TFS DB's.. Got success message but When I checked the TFS DB properties its showing the owner of user who done Restore of DB (But not the User Name who executed this command in application server)

Syntax:TFSConfig Accounts /ResetOwner /SQLInstance:ServerName/DatabaseName:DatabaseName

what exactly the above command will do where can I check result of above command?

Question 2: in above blog requested to execute below command to Update service account for TFS.. But my TFS Service account is Mentioned as "Network Service" when checked in "Application Tier Summary"

Syntax : TfsConfig Accounts /add /AccountType:ApplicationTier/account:AccountName
/SQLInstance:ServerName /DatabaseName:DatabaseName　

For me it's not needed to execute this command right? because my TFS service account is Network Service it's not a custom account?

please help me on this.

Regards,

Naveen M
