Examples

Example: 1

PS C:\> Copy-DbaLinkedServer -Source sqlserver2014a -Destination sqlcluster

Copies all SQL Server Linked Servers on sqlserver2014a to sqlcluster. If Linked Server exists on destination, it will be skipped.

Example: 2

PS C:\> Copy-DbaLinkedServer -Source sqlserver2014a -Destination sqlcluster -LinkedServer SQL2K5,SQL2k -Force

Copies over two SQL Server Linked Servers (SQL2K and SQL2K2) from sqlserver to sqlcluster. If the credential already exists on the destination, it will be dropped.

Required Parameters

-Source

Source SQL Server (2005 and above). You must have sysadmin access to both SQL Server and Windows.

-Destination

Destination SQL Server (2005 and above). You must have sysadmin access to both SQL Server and Windows.

Optional Parameters

-SourceSqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-DestinationSqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-LinkedServer

The linked server(s) to process - this list is auto-populated from the server. If unspecified, all linked servers will be processed.

-ExcludeLinkedServer

The linked server(s) to exclude - this list is auto-populated from the server

-UpgradeSqlClient

Upgrade any SqlClient Linked Server to the current version

-ExcludePassword

Copies the logins but does not access, decrypt or create sensitive information

-Force

By default, if a Linked Server exists on the source and destination, the Linked Server is not copied over. Specifying -force will drop and recreate the Linked Server on the Destination server.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

-WhatIf

Shows what would happen if the command were to run. No actions are actually performed.

-Confirm

Prompts you for confirmation before executing any changing operations within the command.
