  • Module could not be loaded

    • I installed dbatools using
      Install-Module dbatools
      and that went fine but when I try to execute
      Copy-SqlLogin -Source oldserver -Destination newserver
      I get the error
      Copy-SqlLogin : The 'Copy-SqlLogin' command was found in the module 'dbatools', but the module could not be loaded.
      For more information, run 'Import-Module dbatools'.

  • Copy-SqlLogin with -Logins and -SyncOnly parameters -> Error
    1 Posts | Last post January 05, 2017
    • Hi Chrissy,
      When you use Copy-SqlLogin with -Logins and -SyncOnly parameters you'll get the next error:
      Get-ParamSqlLogins : Cannot process argument transformation on parameter 'SqlCredential'. Cannot convert the
      "System.Collections.Hashtable" value of type "System.Collections.Hashtable" to type
      This error is displayed by Sync-SqlLoginPermissions.ps1 because from Copy-SqlLogin you call this script with $loginparms and this is a "System.Collections.Hashtable" value.

      Great tool. I am using Copy_SQLDatabase. I am getting above error, even though I can map the directories on the server, that I am running the function. Appreciate your help in this regard. Thanks
  • Copy-SqlDatabase for only one DB
    2 Posts | Last post November 30, 2016
    • Hi,
      I just discovered dbatool, and it looks great. I have a question however with Copy-SqlDatabase. Is it possible to only copy one specific database from one sql server to another. When I did "get-help -Name Copy-SqlDatabase -Full" I see in example 1 a parameter called -Database which seems to indicate this, however in the list of parameters when i type out the syntax it's not available. It seems that i can only copy all non-support db's or everything including support db's.
      How do you go about doing this for only 1 db, say because you need to upgrade/migrate it do to vendor support?
    • Hey John,
      Yep, it works with just one database. Please update -- I just fixed a population bug. It doesn't show up in Get-Help even though the documentation is there. I didn't know that. PowerShell's native dynamic params aren't great, so we'll be switching to TabExpansion++. Should be by this time next month --its our most often asked question.

  • Logins
    2 Posts | Last post September 21, 2016
    • Hi Chrissy.
      Is there any way to just migrate the logins that belong to a particular database when you migrate the database?
      I saw the option :
      Copy SqlLogin -source sql01 -Destination sql02 -Logins user1 , user2 , User3 , etc. But if you have like a hundred logins !? Would be nice to just " say " i want to migrate login That belongs to "this " database .
      many regards

  • Export-SqlLogin typo in help?
    1 Posts | Last post August 19, 2016
    • Hi,
      Trying out the Export-SqlLogin I kept getting the error "Cannot bind positional parameters because no names were given." I looked at the source code and the file name parameter should apparently be -FilePath not -FileName as the examples have it.
      Great scripts, thanks! 
  • Errors with ReuseSourceFolderStructure and Job Migration

    • Chrissy, many thanks for your beautifully crafted tool. 
      During my tests I encountered following errors:
      Building file structure inventory for 17 databases
      ######### Database: Archive_QA #########
      Start-SqlMigration : Database migration reported the following error Cannot validate argument on parameter 'filepath'.
      The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

      Could this be related to having multiple instances?
      Apart from that everything is fine.
